Loren Brichter, founder of Atebits and developer of Tweetie, has quit his job at Twitter. Twitter purchased Atebits in April of 2010 and immediately put Brichter in charge of developing Twitter’s official iPhone and iPad application.
I follow Brichter on Twitter but missed this tweet. This isn’t a huge shocker. Guys like Loren made a bunch of money before Twitter bought him out, and then made a bunch of money from that. I am sure he enjoyed working on his app at Twitter for a while, but ultimately I am guessing he just preferred having full control to do his own thing.
