So, I wouldn't need the MU version of WordPress if I want multiple blogs and not within the Wordpress 2.0 -2.9 range? However, I have read that you could have accounts that have blogs in your memberships, if you so desire. I think of that kind of akin to Myspace, or Twitter. I did notice Wordpress also seems faster compared to Joomla when I installed it. I don't know how they do it (I'm still in the learning phases of PHP, myself).
I'm thinking of in the future creating a social networking aspect to my website for people to discuss about growth on the web. Don't worry, I'm not into bringing sites like these down. I want it to be an add-on to communities like these for what I do and have a passion for. For this, I would need at least three blog sections: one for personal, one for business, and one for professional blogging.
Everyone who posts has been very helpful and of course I appreciate all these suggestions! I tend to plan how my website will be constructed and I think that's the best way to do it, without walking into deep sand in the future. For all I know, it may go in a different direction then I intended, which is the way most projects end up to be!
