A little while ago I launched Topicala.com. Topicala basically was an extension of my tag directory but it was not specific to my site. I have been thinking over the last couple of weeks (whilst I have been unable to keep topicala up to date) that I might as well make it distributable, i.e that anyone could run the software. So that is what I am going to do.I will release the code shortly, once I have re-deployed it under the kinaln.co.uk domain. And I will make it maintainable and modfiable so that any person can have something similar to www.topicala.com underneath their own site.Let me know if you are interested.
