Well, it seems like yesterday that I launched TwitLi.st, a site that helps you find good people to follow on Twitter. I was playing with PHP and Twitter API the other day (btw, I should have an in-depth tutorial post on that too soon), and made HowTweets.com. (it’s basically the same code running on TwitLi.st but simpler)
Basically it’s a site where Twitter users can hashtag their tweets with #HWT, which HowTweets.com will collect and organize them according to the hashtags used.
