ByteMyCode is an online code and tutorial sharing site which allows users to upload snippets or tutorials containing code and text.
One interesting feature in ByteMyCode is the automatic syntax highlighting which makes the submitted code more readable.
Members can not only submit and share code; they can also revise, comment and rate(Digg Style) other code snippets. Through all these actions, members earn “byte points,” where they can move up the community rankings.
The community as of now is still small and so is the number of code snippets shared/submitted by the users. However the site is worth checking out :). Also if you want to search for source code do checkout Koders !
