Originally limited to advertisers upon launching in 2011, Twitter Analytics has finally opened its stat-tracking doors to all users. Although without a formal announcement, there's always the possibility that it's all a glitch—in which case, get it while it's hot/broken.
Upon signing in with your normal Twitter account and authorizing the app, the Analytics dashboard is supposed to offer all sorts of helpful numbers and graphs that show which of your tweets did best and when. But as of right now, attempts to check our stats haven't give us full results, mostly in falsely claiming zero retweets, replies, or favorites along the top chart.
If this really is open to the public, you should also be able to eventually get full statistics on your followers. Will Oremus of Slate was able to get full location, gender, and overall count data on his, but so far, this screen is the best we've got:
Of course, there's a good chance that this sort of information would take quite a while to roll out and perhaps just got turned on a little too soon. We've reached out to Twitter for comment on the matter, but until we know if this helpful little tool here to stay, might as well suck up whatever data you can.
Update: Twitter gave us the following statement about the newly opened Analytics—looks like it could be here to stay, after all:
We've been experimenting giving the analytics feature to a small groups of users outside our advertising clients. We've been happy with the response thus far, and will determine next steps after the conclusion of these tests.
