I have used several different blogs and gotten a LOT of traffic from technorati, and I get banned sometimes. I tend to think that participating in a public technorati exchange is a bad idea, but you need some authority now to get anywhere with Technorati, even if you are making really good content for their folks. I did in fact just exchange a fave with somebody here at DP (my first exchange), and I have no problem with that. But, if you check out the links at Dosh Dosh's famous Technorati Favorites Exchange from a while back, a lot of those sites don't look to me like its done them much good. Tell me if you think its a good idea or not. I really need some technorati authority but I;m trying to create a sustainable site.
