First-Time Blogger

I am usually pretty up-to-date with the latest innovations with technology. Blogging however is very new to me. While I have read several blogs on sites such as MySpace and Facebook, I have never actually created my own blog. Since this a new experience for me, I am open to any feedback or ideas as to what types of things make for interesting posts to add to a personal blog. I was planning on using my blog as a place to post teaching ideas and resources that I use and would recommend to fellow teachers.
