As far as finding blogs people actually read, probably a blog ranking site would be a good start http://www.blogmetrics.org/crafts
One thing about good craft blogs is that there are tutorials galore. Tutorials are very, very tedious to put together. However, if you want to rank, you have to do it.
Another way to do it is just to become a referral/resource site (a corresponding pinterest and/or tumblr would work well there). You could link to other sites that have the tutorials you like. I would put "with free tutorial" somewhere in the title of each post so folks can easily spot them when browsing.
