Share some of my what? You need SEO blogs that help you improve your rankings? Here are a few that I read daily: http://www.seomoz.org/blog http://www.wolf-howl.com/
you can try building web 2.0 like quizilla,squidoo,live journal and blogger just make sure to put different and unique contents.
DP forum is one of them, i get lots of information years ago but now seems less and less quality post appear
Seomoz is my favorite as well. Of course there is many nonsense posts from gurus as well, but if you know how to filter information, you can really learn a lot there!
