TwitPic, the photo-sharing service, is shutting down rather than fighting against Twitter's recent legal demands.
Founder Noah Everett explained Twitpic's unexpected demise:
A few weeks ago Twitter contacted our legal demanding that we abandon our trademark application or risk losing access to their API. This came as a shock to us since Twitpic has been around since early 2008, and our trademark application has been in the USPTO since 2009.
If you use Twitpic, you'll be able to export your old photos and videos before it shuts down. Get your "RIP TwitPic" tweets scheduled for September 25th... unless you're boycotting Twitter in protest.
I've asked Twitter to explain their decision and will update when they respond.
