Blogging Dilemmas

I have to admit I am questioning my blogging abilities. The concept of keeping a blog I do find very intriguing, but most of the time I feel that what I am writing about is irrelevant. Right now as I look for a job blogging is in the back of my mind, especially entering the job market with a communication degree. The ability to keep a blog, or something like a blog, is going to be a selling point for businesses in the near future. The idea of integrating social networks and blogs with corporate america is a fast growing trend. I enjoy keeping up on my knowledge about how they work together, but I think I still have a lot to learn =)!
