Along with Twitter, I also post some of my favorite links to a new Facebook page. If you visit the actual blog, you may have noticed the Facebook badge on the right. The page holds links and you can comment on them. If you find any useful, I'd love to hear it.
The Facebook page also has a discussion area. If there are any burning topics that someone may help with or for which you'd just like to see anyone's thoughts, then perhaps posting on the discussion board would be useful.
I hope to hear from you instead of just talking to myself!
