Within certain demographics, twitpic is more popular than flickr. It may not even be that hard to find people who use twitpic and don’t even know what flickr is. Another advantage: if you’re using twitter, it’s easier to get started with twitpic than with flickr, since you don’t need a new account. Obviously this does not apply if you were using flickr already.
