FeedStitch offers multiple third-party ways of logging into the service including using Twitter, Facebook, Google, Yahoo, Open ID and AOL. Once logged in it is possible to paste RSS feed urls into the form to add them into groups. Groups are made up of multiple RSS news feeds and other news sources and provide access to a single RSS news feed url or Json item.

The other news sources that can be added in addition to news feeds are Twitter (either by username or Twitter search), Flickr, Delicious, Github and Tumblr. A new url is created for each new group that gets created by the user. Each group can be accessed directly in the web browser or in a feed reader. It is also possible to customize the url in the form http://feedstitch.com/groupname/.

FeedStitch is a nice service for users who want to quickly combine multiple RSS feeds into one especially if they have an account at one of the services that can be used to log into FeedStitch.
