If you weren't aware of it already, there's a useful tool named SocialMarker that allows you to semi-automate your social bookmarking submissions. SocialMarker allows you to customize which sites to which you want to submit, including "dofollow" social bookmarking sites. It works well, helps get backlinks, and it's completely free.
yes, it is an useful tool. you have to signup with each site before you can submit tho. using firefox browser and set to remember PW helps and you dont have to loging to each site everytime you submit a story page
I find this a very useful tool indeed. In fact, if I add a new page to my websites and want it indexed quickly I use this together with propeller and digg. It can get pages indexed with Google in a matter of hours. . Works every time, I only submit to the Do Follow sites.
