Do you Tweet?

I've been using Twitter (cctechie) to widen my Personal Learning Network for about a year now. I tend to read much more that I actually post but I've been trying to share more. Today I read a blog post on Edutopia by Betty Ray that describes how to use Twitter to grow your PLN. Her post is a good resource for those just starting out with Twitter or who need a few ideas to get more out of this good PLN resource. So... do you Tweet?
