should I do bookmarking of my blog posts in blog network?

[Pulsar Sandhu]

I bought a monthly service on high PR blog network but my rankings have not improved even a bit. Should I experiment with the posts by dripping 30-50 bookmarks daily on these posts? Please advice some thing else which may benefit me..

A number of the more highly publicized private blog networks designed exclusively for search manipulation were recently removed from the search indexes. Some don't bother to tell their clients that their effectiveness has been wiped out.

Social bookmarking sites like Digg Redit may also have a small search rank benefit, there are posting services that speed the process, SocialAdr.com is one with free or paid services that get other people to book your posts on their accounts which may be more powerful than just using your own account, they also have a text spinning function to make each post copy unique. I don't recall seeing traffic from social bookmarking sites, but they may still be some search ranking benefit, the real payoff is being a featured item on te hi pr front page of the site.
