First thing you need to know who are your targeted audiences. I believe you want to make some money from it. If you really wanted to make this go, choose particular field and spend your quality time. Purpose of blog is not to dump everything on same place, but to provide information about specific subject matter. If your purpose is to touch every fields and provide all kind of information then start thinking about PORTAL like yahoo.

One more thing i dont like the URL. URLs should be very catchy and easy to remember. Your URL is not user friendly.

Just my thoughts. No offense. Good Job keep it going.
