Meerkat is a Web-based syndicated content reader. It is based on RichSiteSummary (RSS), an XML specification used for distributing news, product announcements, discussion threads, and other assorted content as channels. Meerkat provides a simple interface to these stories. While maintaining the original association of a story with a channel, Meerkat's focus is on chronological order -- the latest stories float to the top, regardless of their source.
Technically, Meerkat is one [Dictionary:Meerkat word], but we break it up in the grand tradition of "NetScape."
