Hwy are there no negative options in th epoll.
I personally refuse to use these systems. Part of it is spamming (Sending your web address to lot of people, in the hope that [part of them comes to your site, thus generating traffic) and because I still believe firmly in having a good product.
I do not do well ion search engines. Granted. Except of course my personal website, which I abandoned 5 years ago, and still reaches high scores (Top 5)
My prof. domain doesn't get high hits in search engines (~10-20) but does get appr. 10-20 000 visitors /month trough links & webrings. So I see no need.
