My top social bookmarking sites

Every day I use a variety of social bookmarking sites. Not only do I use these sites for personal interests, but I use these sites to gain backlinks for my network of websites. For webmasters out there, you should have accounts at all of these sites.

Over time these sites can generate thousands of impressions daily, so if you value free and valuable impressions you should pay attention to these sites.

Here are my favorite social bookmarking sites listed in order of importance.
