Ideagraph version 0.5 beta - an RDF-based Personal Knowledge Manager, (far from finished, web pages also under construction). Feedback sought. Completely fresh version available for download, Java-based so any platform.

Source will be available for non-commercial use in a couple of days.

PS. It's a priority for me to get the blogging/RSS facilities of it in place, so I can run this blog from it and don't have to keep messing with Perl scripts to keep the feed working...
