Is it a good idea to submit urls to pligg sites. It seems social bookmarks are becoming what blog comments have become a year ago. They will rather hurt your site than help you move to the top. Is it true? A lot of BHW services still provide social bookmarks as part of their sefvice. Won't that hurt the customer? MAybe its better to concentrate on forum profiles? Forums get spammed too, but at least your profile page is isolated from other profiles, and looks rather ok, while pligg pages look like a spamfest. Are you still using pligg in your campaign?
