Trackbacks offer an advantage to anybody who comments on your blog - they get a link back to their own blog. If you don't have trackbacks, they're just gonna post a comment on your blog, but you will get no link from them. If you don't have comments either, they're not gonna do anything, I guess
Of course, they could take the time to write a post about how great your site is, but I think they would only do this if they really loved your site, and maybe not even then. However, if you have trackbacks enabled, they will eagerly do it, since they would get a link back. How else could we get to have millions of visitors per month?
I can't imagine anybody setting asside half an hour to write a piece telling people "Hey, there's a guy from Romania called Dan who has a great website on self healing - check it out". Maybe that's why it doesn't happen, cause I don't believe it can.
As for a forum, I know I wouldn't need one right now, cause I only have 27 visitors a day. But I thought you did have enough visitors to make it worth it. Even 10 people could make for an interesting discussion, I guess.
I want to create a great blog and forum in Romanian, and here I hope to attract more people, since the field is not well explored.
