I'm toying with the idea of a multi-author Java tips blog, and am looking for possible contributors. If there is sufficient interest, I'll be able to setup a subdomain to host the blog.
Please do contact me at redemption at codefront.net should you be interested. This is (what I foresee) a good opportunity to share your experience and expertise with the Java community via the informal weblog medium.
UPDATE: I've setup a subdomain at http://javatips.codefront.net/.
