My very first blog

So i am a member of a Blackberry users group call BerryStalkers. (yes i am a Crackberry addict) One of our founding members was talking about starting a blog page from within the group. One of our other members is willing to host it for us. I was thinking that it would be a really fun idea to have one. BUT. I really no nothing about blogging per se. I hear the word tossed around everyday on tv and of course the internet. Blogging seems to be a normalcy of life on the internet yet i know nothing about it . So hear i am starting from scratch trying to learn as i go.... If anyone has any tips or tricks to make this blogging experience more enriching, please don't hesitate to share your words of wisdom with me.... It will be greatly appreciated....
