A good change for most! Inconvenient for others.
This morning marked the official deprecation of Twitter's basic authentication system. I had been working toward the changeover, and at about 8 am I switched iTweet.net over to OAuth-based authentication.
Things went pretty smoothly, I hope. Most people seem to have been able to refresh, authenticate with Twitter, and start tweeting again right away. Even aside from the improved security, the nicest immediate benefit is the API rate limit of 350 calls per hour instead of the 150/hour available through basic authentication. This will allow me to do some fun stuff that wasn't possible before.
The people who were most affected by this change were those who use iTweet because twitter.com is blocked due to a company firewall/filter or censorship. These folks are not able to sign in via OAuth, just due to the nature of what OAuth is. I'm bummed that this is the case, but don't immediately see a way around it - however I am open to ideas from any direction.
For the time being I've put a basic-authentication version of iTweet up at:
http://itweet.net/basic/ - and you can use it at that address for the next two weeks.
However, please note that Twitter is going to be cutting down the number of available API requests by 10% every business day until August 31, when basic authentication will be switched off entirely. You can read about this in the twitter-development Google group. If you're one of the folks who use iTweet to get around a filter, this is a bummer.
So by the end of the month people needing a proxy for twitter.com will be out of luck. I'm open to suggestions as to how this inconvenience could be avoided, as this change will happen for all apps, not just iTweet.net - feel free to post ideas in the comments.
