I am not an seo person. What I do know is that meta tag is not enough. The engines like to read text on a page to tell if its relevant to what the surfer requests.
You will receive hits from the lists for the people that go there. But you also want a surfer to come across your site from one of the big engines like google, msn and yahoo. You will only get that by writing on your page.
Take a look at some sites at LOR or others to get a feel for what is done. Also look in the seo section of this board and read some of the posts for more info on this matter.
Good luck
