Tiny Tiny RSS is a RSS Feed Reader, based on the technology of PHP and Ajax. It is different from any Window-based RSS reader, Tiny Tiny RSS users only need to use their browser to read their RSS Feed. It supports popular RSS, RDF, ATOM feed formats. You can combine any RSS feeds and generate OPML file (for quick sharing). With a tiny change of the program, you can switch Tiny Tiny RSS into multi-user mode. All users can have their own RSS feed and optionally share with other users on the same system.
