I use Twitter Search every week, sometimes every day.
So I’m very experienced in its past shortcomings. Most of the time, it’d crap out after a week or two worth of tweets. For some obscure searches, you’d be lucky to get a month (which would be a handful of tweets).
Today, the incredible happened. It went back to 2011:
Click = big
And I ran another search, a vanity one — because I know what I tweeted over the years — and that search went back to 2009!
Twitter Search is now a real research tool!
