I have blogs on blogger and wordpress and am curious to see how this will fair. I think much of the seo
disadvantage of tumblr comes down to people using other people's reblogged content. As I'm not oing to do that, I don't think I'll suffer a disadvantage. If it turns out that I do, I'll transfer it to wordpress, as there are a few tumblr to wordpress conversion tools out there.
If/when I get to 10,000 views a day I think it'd be possible to make CMP ads worthwhile (valueclick etc) or maybe google ads will suffice, not sure yet. It achieved around 1000 pageviews yesterday, which isn't bad considering I've only just started working on it.
