TwitPic is shutting down. For the uninitiated, TwitPic was the de facto place to post a picture on Twitter back in the good old days of 2008. This was years before Twitter had its own photo service.
From The Verge's piece on the news:
In a blog post announcing the service closure, Twitpic’s Noah Everett notes "Twitter contacted our legal demanding that we abandon our trademark application or risk losing access to their API." The move shocked Everett "since Twitpic has been around since early 2008, and our trademark application has been in the USPTO since 2009." Twitpic doesn’t have the resources to battle Twitter legally and Everett has decided to shut down Twitpic instead.
Twitter as a company is turning into a bully. Plain and simple.
