As we resign ourselves to the fact that the post-Oprah Twitter is undeniably mainstream, the SawHorse sites become an interesting way to parse through the different microcosms and communities that exist in the wider web of sites and blogs. Think of them, if you will, as the new web rings.

GiantRedCarpet.com curates tweets from silver screen luminaries such as Ben Stiller, George Clooney, our own Wil Wheaton (he'll always belong to the geeks), and, obviously, the ubiquitous Ashton Kutcher. So you can follow him without, you know, following him. It also gathers updates from "gadfly" Perez Hilton, several athletes, director Kevin Smith, and a surprisingly diverse collection of musicians from Ashlee Simpson to Yoko Ono. I guess what they say is true: Everybody really is doing it.

ThePetFeed.com is simply freakin' strange. We've heard before about people who set up Twitter accounts for their animal companions. This site is their mothership, an aggregation of the passing thoughts of cats, dogs, birds, rodents, and one lonely capybara (go ahead, click the link, you know you have no idea what a capybara is).

After a long and thoughtful pause, all we can say is good on you, SawHorse.
