Is Twitpic the first Twitter app to be GFW’ed? And should anyone care?

This is somewhat in response to Ben Parr’s Mashable article and the subsequent comment stream, and following up on a thought I had last night after hearing about Twitpic being GFW’ed. In case you haven’t heard, after yesterday’s explosion, Maggie Rauch posted a few images of the rubble and the police response to Twitpic. The images quickly made the rounds on Twitter and soon thereafter Twitpic itself was blocked in China.

Any website getting blocked is not really surprising (or big) news (lots of ways around that Wall after all) but it got me to thinking if this was the first Twitter app to be blocked in China? Twitter itself is occasionally blocked of course, and its API has been blocked, but to my knowledge (nothing shows up in search results, but please correct me if I’m wrong), Twitpic seems to be the first app – especially a major one – to be GFW’ed itself independent of Twitter. Of course, none of this really impacts anyone too much as not even Twitter is widely used in China, nevermind Twitpic (that said, would be interested to see what Twitpic’s China traffic – if it’s significant at all) is.
