I am starting to post in Twine.com. Twine is a new service for sharing and discussing information around mutual interests. It's like blogging but more interactive, and there is more community. Also, Twine uses the Semantic Web to automatically organize information and help you discover content around your interests. Twine is the product of my son's company, but that's not why I'm using it -- it's actually really useful.
Note: Twine is still in invite-beta, which means you have to register and then get invited in, but it's free and they will be opening it up soon -- so join and then once you get in join my twine and let's connect. I'm looking forward to getting to know my readers.
