RSS 2.0 is currently the most deployed syndication format. The RSS 2.0 spec is currently locked, so RSS 2.0 has gone as far in the specification as it will. That is why many people are putting their money on ATOM feeds instead.
RSS 2.0 suffers some from the strong efforts to make it backward compatible with older versions of RSS. Some will argue that none of the RSS specifications are compatible, but from a general sense, RSS 2.0 is compatible with any previous version of RSS.
Every news aggrator out there will support the RSS 2.0 format, making it a favorite for syndication of content. The next version of Internet Explorer (IE 7) and even the next version of Windows (Vista) will natively support RSS feeds.
