My experience with Blogs

Hi everyone. This is my first attempt at creating a blog. I have worked using the Internet for many years and have read many blogs (mostly political) but have never taken the opportunity to start one. I will confess I have a desire now to start one for teaching and another one for venting about hwere our country is headed (not a good place, I'm afraid). I have observed many podcasts and wiki pages but again I have only worked on these as an observer or collector of information. I have heard that these tools were available in the classroom but never actually saw one in use before. I can see where this could really play a role in communicating with parents and students without violating any rules.
