More trouble in blog city: Turns out, it only takes four inbound links to get you placed into the 22nd spot on Blogdex these days, and just 7 to get into the top-10 -- and once you do, you've successfully cracked into yet another direct RSS channel bound for auto-sidebar space on a host of blogs.

At the very least, I should think Blogdex might discount links coming from the same base domain name. Hard to imagine any useful scenario where such links would have any semantic meaning of importance -- except maybe Salon/Typepad bloggers citing each other.
