I don't understand something. Why don't site owners help each other out? What I mean by that is what if I went to a site owner (that I respected) with a somewhat similar site and said, "I'll drive traffic to your site if you drive traffic to my site." We might be able to push a few hundred visitors to each other each day. Now imagine if I did that with 5-10 other sites. All of a sudden I've got a 1,000 new visitors every day for almost no work. I don't see anyone doing this? It seems like a good idea to me. What do you guys think?
