Reviewing the announcements from the Google Blog last week, I came across a note about their new blog pinging service. This post is to see whether Windows Live Writer will work with it “out-of-the-box”.
Update: I tried configuring the ping URL in Tools -> Preferences to be
http://blogsearch.google.com/ping/RPC2 and my URL does indeed appear in the changes feed (for the past 5 minutes), so I assume that worked. Just add that Google URL to the list of pingable endpoints in WLW.
