FAQ
How do I use it?
To use GTweet, click the "Sign in with Twitter" button at the top of this page. You will be taken to Twitter where you can grant GTweet access to your account without ever giving GTweet your username and password.
To add a feed to Google Reader, click the corresponding 
button on your profile page.

How does it work?
GTweet acts as a bridge between Twitter and Google Reader. It never stores any tweets. Essentially, GTweet turns your twitter streams into an RSS feed that does not require authentication, which you can then subscribe to in Google Reader.
You'll notice that your GTweet URL contains a long string of gibberish separated by dashes. This is your unique identifier that you should keep private. It correlates to your Twitter OAuth token which is stored by GTweet so that it can be used to fetch your twitter feeds.
Your Twitter password is NEVER stored anywhere by GTweet. Please see the GTweet Privacy Policy and the Google Privacy Policy for more information.
Why am I missing protected tweets?
In deference to the tweeter's privacy and the wishes of Twitter, users who protect their tweets will be filtered out of GTweet feeds starting May 15, 2011.
To be clear: even if you have access to the protected tweets on Twitter, they will not appear in any feed created by GTweet. This change was required for compliance with the Twitter API TOS.
How often does Google Reader Update?
It is not possible to specify how often a feed is updated in Google Reader. GTweet feeds are rendered with the lowest possible TTL value to entice Google to update them more often.
Wasn't this already possible?
Twitter's native RSS feed requires authentication, so the only way to add it to Google Reader before was to use a service like freemyfeed.com.
While freemyfeed is a great (and free) service, it was not designed specifically for Twitter. As a result, the unaltered feed from Twitter that is presented in Google Reader is pretty ugly: urls and @screennames contained in the tweet are not turned into links, the tweeter's avatar is not displayed and there is no way to reply to or RT a tweet.
Who's responsible for this madness?
GTweet was created by Adam Jarret. Check out adamjarret.com for my blog and other projects and be sure to follow @adamjarret on Twitter.
