Hello All ...yes I'm back with more questions

haha ....but I will say this before my questions, I have learned so much from this forum it's unreal ! Everything I thought I knew ...I really didn't. There is so much information to absorb ...so many great resources..and such great people to offer their expertise and help along the way for people like me ...full of who, what, when, why, and HOW in the world do I's ...LOL I can't thank you all enough for the help you have provided me on my learning adventure !
So with that said ...My questions are, If I were to assume that in some fashion using Facebook statuses, Threads on here, Myspacing etc. are in fact some form of Blogging, correct? If this is true, than I am not as lost in the blogging world as I thought. What would be the right topics for a Virtual Assistant to Blog about? Does it have to be aimed at the clients, or other up and coming VA's, can it take a personal direction? For a Blog to be successful, and gain the readers/followers I got the jist of Blog ideas such as, ask questions, having guests post, responding to something else on the web, having polls ...but about what ? I could really use some suggestions here ...so I can get my creative writing hat on, should I pick to do research on a topic and write my opinions ...what are the appropriate boundaries for blogging in a Virtual Assistant Business? How often do you update your blogs? How do you know what to blog about next?
I have searched the web, trying key word searches for what I am trying to understand about Blogging, but I just haven't found the answers I'm looking for.

So in posting this thread, I am hoping that you all can again assist me in learning a little bit more.
Thanks so much for any advice, suggestions or ideas you may have on VA Blogging.
