User timeline, Twitter search, and user favorite RSS feeds can now be generated with Pixsy using the following commands:
Twitter Search Feed:
.twitter -rss [enter search term(s)]
Twitter User Timeline Feed:
.twitter -rss-u [enter Twitter user]
Twitter User Favorites Feed:
.twitter -rss-f [enter Twitter user]
This generates encoded URL's that you can enter into your feed reader. Hope that this helps! You can find Pixsy at http://www.pixsy.net/.
