How different are these from things like the old DayPop top-40 lists, etc.?

TailRank is my current favorite because it goes beyond this to give a Social Network Context.

Old cases:

• DayPop doesn't use RSS, it just scrapes the front page .

• Same for BlogDex.

  • Yuck, I just realized that since BlogDex and DayPop focus on the home/front page of each blog, if you just put summaries on the front page, with a "More..." link to the fulltext (or, as in my site, have a separate Wiki page), the external links don't get picked up!
