Anyone who wants to do an analysis of the biblioblogosphere (Hi Walt!) will want to try this out:
FeedZcollector is an application that captures the content of web feeds (RSS, ATOM and RDF) at regular intervals. The content is stored in a Microsoft Access or MySQL database, ready for you to analyze, process or present.
So it looks like you just plug in the feed URLs and it’ll check the feeds and store all contents in an MS Access or MySQL database.
I’m going to be keeping an eye on on the FeedZcollector blog– this could be really, really cool.
