I joined Twitter on February 21, 2007, at exactly 15:14:48, and I created my account via the web interface. As you can see, my first tweet was pretty mundane!

I remember discussing this exciting cool “new Web 2.0 site” with Kim Plowright @mildlydiverting in Roo’s office in Hursley a couple of days before, and before long he, Ian and I were all trying this new newness out. It was just before the 2007 SXSWi, where Twitter really started to get on the radar of the geekerati.
But wait a moment! It’s impossible to pull back more than just over the last 3,000 tweets using the API, so how was I able to get all the way back to 5 years ago and display that tweet when I’ve got over 33,000 of them to my name?
It’s a relatively little-known fact that you can ask Twitter to disclose everything they hold associated with your account – and they will (at least, in certain jurisdictions – I’m not sure whether they will do this for every single user but in the EU they are legally bound to do so). I learned about this recently after reading Anne Helmond’s blog entry on the subject, and decided to follow the process through. I first contacted Twitter on April 24, and a few days later faxed (!) them my identity documentation, most of which was “redacted” by me Yesterday, May 11, a very large zip file arrived via email.
I say very large, but actually it was smaller than the information dump that Anne received. Her tweets were delivered as 50Mb of files, but mine came in nearer to 9Mb zipped – 17Mb unzipped. I’d expected a gigantic amount of data in relation to my tweets, but it seems as though they have recently revised their process and now only provide the basic metadata about each one rather than a whole JSON dump.
So my entire archive of Tweets back to Feb 2007 is a ~8Mb text file (140 chars per tweet+metadata).—

So, what do you get for your trouble? Here’s the list of contents, as outlined by Twitter’s legal department in their email to me.
- USERNAME-account.txt: Basic information about your Twitter account.- USERNAME-email-address-history.txt: Any records of changes of the email address on file for your Twitter account.- USERNAME-tweets.txt: Tweets of your Twitter account.- USERNAME-favorites.txt: Favorites of your Twitter account.- USERNAME-dms.txt: Direct messages of your Twitter account.- USERNAME-contacts.txt: Any contacts imported by your Twitter account.- USERNAME-following.txt: Accounts followed by your Twitter account.- USERNAME-followers.txt: Accounts that follow your Twitter account.- USERNAME-lists_created.txt: Any lists created by your Twitter account.- USERNAME-lists_subscribed.txt: Any lists subscribed to by your Twitter account.- USERNAME-lists-member.txt: Any public lists that include your Twitter account.- USERNAME-saved-searches.txt: Any searches saved by your Twitter account.- USERNAME-ip.txt: Logins to your Twitter account and associated IP addresses.- USERNAME-devices.txt: Any records of a mobile device that you registered to your Twitter account.- USERNAME-facebook-connected.txt: Any records of a Facebook account connected to your Twitter account.- USERNAME-screen-name-changes.txt: Any records of changes to your Twitter username.- USERNAME-media.zip: Images uploaded using Twitter’s photo hosting service (attached only if your account has such images).- other-sources.txt: Links and authenticated API calls that provide information about your Twitter account in real time.
Of these, let’s dig a bit more deeply into just a few of the items, no need to pick everything to pieces.
The “tracking data” is contained in andypiper-devices.txt and andypiper-ipaudit.txt – interesting. The devices file essentially contains information on my phone, presumably for the SMS feature. They know my number and the carrier. The IP address list tracks back to the start of March, so they have 2 months of data on what IPs have been used to access my account. I’ve yet to subject that to a lot of scrutiny to check where those are located, that’s another script I need to write.
I took a look at andypiper-contacts.txt and was astonished to find out how much of my contact data Twitter’s friend finder and mobile apps had slurped up. I mean, I don’t even have all of this in my address book… given the fact that the information contained the sender email addresses for various online retailer newsletters, I’m guessing that Google’s API (I’m a Gmail user) probably coughed up not just my defined contact list, but also all of the email addresses from anyone I’d ever heard from, ever.
Twitter has on record 981 phone numbers and 8741 email addresses from my contacts / when I've used Find Friends :-o deleting that...—

Fortunately, there’s a way to remove this information permanently, which Anne has written about. I went ahead and did that, and then Twitter warned me that the Who To Follow suggestions might not be so relevant. That’s OK because I don’t use that feature anyway – and in practice, I’ve noticed no difference in the past 24 hours!
I use DMs a lot for quick communication, particularly with colleagues (it was a pretty reliable way of contacting @andysc when I needed him at IBM!). That’s reflected in the size of andypiper-dms.txt, which is also a scary reminder to myself that I used to delete them, but since Twitter now makes it harder to get to and delete DMs, I’ve stopped removing them and there’s a lot of private data I wish I’d scrubbed.
Taking a peek at the early tweets in andypiper-tweets, I’m trying to remember when the @reply syntax was formalised and when Twitter themselves started creating links to the other person’s profile. Many of my early tweets refer to @roo and @epred and I don’t think they ever went by those handles. 5 years is a long time.
I mentioned that the format used to deliver the data appears to have changed since Anne made her request. She got a file containing a JSON dump of each tweet including metadata like retweet information, in_reply_to, geo, etc etc.. By comparison, I now have simply creation info, status ID (the magic that lets you get back to the tweets via web UI), and the text itself:
******************** user_id: 786491 created_at: Wed Feb 21 15:43:54 +0000 2007 created_via: web status_id: 5623961 text: overheating in an office with no comfort cooling or aircon. About to drink water.
It’s a real shame that they have taken this approach, as it means the data is now far more cumbersome to parse and work with. However, using some shell scripts I did some simple slicing-and-dicing because I was curious how my use of Twitter had grown over time. Here’s a chart showing the numbers of tweets I posted per year (2012 is a “to date” figure of course). It looks like it was slow growth initially but last year I suddenly nearly doubled my output.
Still considering what other analysis I’d like to do. I can chart out the client applications I’ve used, or make a word cloud showing how my conversational topics have changed over time… now that all of the information is mine, that is. It is just a shame I have to do so much manual munging of the output beforehand.
Oh, and the email I received from Twitter Legal also said:
No records were found of any disclosure to law enforcement of information about your Twitter account.
So, that’s alright then…
Why did I do this? firstly, because I believe in the Open Web and ownership of my own data. Secondly, because I hope that I’ll now be able to archive this personal history and make it searchable via a tool like ThinkUp (which I’ve been running for a while now, but not for the whole 5 years). Lastly… no, not “because I could”… well OK at least partly because I could… because I believe that companies like Twitter, Facebook, Google and others should be fully transparent with their users and the data they hold, and that by going through this currently-slightly-painful procedure it will encourage Twitter to put in place formal tools to provide this level of access to everyone in a frictionless manner.
If you’ll excuse me, I’m off to dig around some more…
