I haven't posted much the last couple of days because I've been working hard on my latest Radio tool. It's called liveTopics and you can see the results on this page. Some of the postings have a new Topics: section under them with links from various topics that the postings are related to.
Each link goes to a central Topic Table of Contents for my weblog. Where you can see all the postings related to a particular topic grouped together.
The tool also provides automatic generation of META tags with keywords and a "what i'm talking about" banner showing the topics associated with recent postings.
It should start being tested in the next couple of days and, if all goes well, I hope to release it next week.
