evectors announces k-collector version 1.0, an RSS aggregator aimed at the enterprise market. If you haven't seen k-collector in action, it's worth checking out. The aggregator organizes weblog entries on four dimensions: what (subject/topic), who (as subject or author), where (events, geographic location) and when (date of publication). More about k-collector from their "About" page:

k-collector is an enterprise news aggregator that leverages the power of shared topics to present new ways of finding and combining the real knowledge in your organisation.

Weblogs are most commonly published by individuals and organised chronologically. This presents a challenge when considering weblogging in the context of business groups which might expect information to be organised in more meaningful categories. The k-collector architecture, and applications based upon it, deliver an interface targetted at business users.

The k-collector archicture combines clients for leading weblogging software with a server based aggregator and web application. WWWW is the first such application and is aimed at small business groups.

An author can associate posts with relevant topics such as project names, people, etc.. The server automatically shares each newly created topic with every other user allowing them to use those topics themselves. News topics are created in one of four intuitive categories: Who, What, When, and Where. The server then uses these categories and topics to provide an effective interface for navigating posts.
