I can see the potential benefits of using SideWiki. As Clay Shirky said, "Every webpage is a latent community".
As far as robbing bloggers of their comment space, Google Notes can do that. Facebook does that. FriendFeed does it, etc. It's not new, and I'm not sure that it's evil.

I've written before about the compromise we tacitly agree to when amateurs take over the roles formerly held by professionsals . The Internet promotes this takeover by lowering the cost of production and transmission to near zero for nearly every user, for everything from words (blogs) to pictures (Flickr) to video (YouTube).

It is at this point that many people interject: "This is the problem with the internet! It's full of crap!" Many would argue that without professional producers, editors, publishers, an...
