Here’s an interesting one. R-Echos is like the bastard child of Eyebeam’s ReBlog and Cameron Marlowe’s Blogdex. It’s a hack of feedonfeeds like ReBlog but it also shows statistics of words repeated over 20 times from the incoming RSS feeds. One thing I can’t find on here is any archives, but maybe thats because the feeds are taken from other sites.. bur ReBlog has one so umm, I’m confused.
