A useful new web service to complement this would be a site to determine which tweets are censored in which countries and publicly log them for convenient searching and analysis.
Even though I don't like it a bit that they're yielding to censorship, they did the best thing you can do when forced to censor: stay transparent about it. Provide a public API.
Same with the subpoenas: They were forced to give away the user's information, couldn't help that, but they did notify those users, and publish the subpoena.
Despite claims, Twitter is certainly not evil and secretive here.
