Accidentally went to gutmeat.com at first. Not bad. I thought the screenshots were live and broken at first. Need some sort of obvious wrapper/fade around them. Where is the list of events for other people to read?
I would rethink ad-supported. I cannot see you creating an eCPM greater than you advertising CPM in less than 6 months without an incredible viral model. And a lot of the successful viral apps are looking for revenue outside advertising, because they are not making enough on advertising alone.
I see my blog as a resume, portfolio and a networking activity rolled into one. Resumes and portfolio do not tell others how you think, or what interests you nearly as well as a blog. And a blog is social and sharable, so it helps you make new contacts.
