Found a nice article that may help some folks get a bit more traffic to their blogs. Thought I'd share. .. "We all want to know how to get more traffic to our site, make more eyeballs stick, and make more money, but if you keep using the same techniques that have grown out-dated, you're bound to stay at the bottom of the heap. Therefore, here's a brief tip on how to use a lesser known feature of blogs called "trackbacks" and "pingbacks" to get more clicks rolling your way." .. http://www.dummysoftware.com/blog/post48.html
aww.. I think, the article lack some explanation on other features and other aspects. And you are right, some disabled their trackbacks because of those spammers. so I hope there is a better way to get higher traffic than that
