Re: Member blogs
The most important thing is good SEO for giving good rankings on search engine. I dont think blogs are any good for this. I cant ever remembering seeing a blog in any search results I have done. If you are serious about selling your works online you really need a website with good SEO.
I recommend statcounter.com for seeing who is visiting your site and what they do when they are on it. It even tells you which search engine they used to find you, what search words/terms they used to find you (most important thing for SEO), and very useful, where you ranked in their search results
