confusion

I have just added a couple of new RSS feeds to my google reader - Chrystie Hill and David Lee King. I find what they write interesting but I'm also hoping that they will help me understand all this. I am getting more and more confused.
Should I now be using twitter? Is it more useful than blogging. It has been described as what you do between blogging but I don't get it yet.
Will all this help me reach my clients? I don't know. I completely believe that we need to use these new technologies to get to our younger and/or tech savvy clients but which ones? and how?

I really feel that I need someone to sit down with me and explain it all, how these are used and how I can use them in my working life?
Does anyone else feel the same way?
