Data Mining Blogs by Sandro Saitta.
From the post:
I posted an earlier version of this data mining blog list in a previously on DMR. Here is an updated version (blogs recently added to the list have the logo “new”). I will keep this version up-to-date. You can access it at any time from the DMR top bar. Here is a link to the OPML version. If you know a data mining blog that is not in this list, feel free to post a comment so I can add the link. Also, if you see any broken link, please mention it.
Consider this a starter set of locators for a custom web crawl on data mining.
RSS feeds are great, but only for current content.
