good idea to start a new blog! on one hand it's sad to leave the blog you started with behind, but on the other it will also open new doors and new fresh ideas! i must say till so far it looks pretty professional, go on this way!
I see it in the same way. I think i have over grown the old blog and it also didn't gave the pleasure to post. It is a weird feeling. Well, i like that you see the new blog in that way. :) It was one of my goals to have a more professional blog.
