I haven't kept up on the streaming API but read about the new Site Steam and it raised some privacy concerns. Specifically the fact that direct messages would be streamed from anyone that added your application. I understand this was always possible but the stream API makes it fairly trivial to collect all that data.
It's also a privacy concern because of user intent. When someone adds an application my guess is that they're not intending on saying "yes, gain access to my direct messages" much less "sign up to receive all my direct messages via a stream". Anyways, the stream API is awesome...but it's important to understand how users interact with applications and what their intentions are when they add (regardless of what they are in fact signing up for). I also realize all of this was previously possible but by making it easier it increases the chances that apps are accessing this data. Just thought I'd bring it up for discussion :) -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk?hl=en
