Social bookmarking is all about tagging, or bookmarking, sites or web pages of interest. The sorts of sites that feature well in this medium are ones with funny videos, latest news, frequently updated, interesting niches, etc.
These sorts of sites are popular on the likes of Digg, Netscape, Stumbleupon, et al. Once they become popular the effect just snowballs as more visitors to the social bookmarking sites click through to take a look and then give a positive vote.
Social networking sites, on the other hand, are more about community. Here website owners, typically bloggers, gather and form friendships and groups with others who have similar interests.
They tend to view each others sites and explore them more than the social bookmarking crowd. Frequently updated content works well in this case too, though having some depth to a blog is generally of greater importance.
Some social networking sites are -
- MyBlogLog
- Spicy Blog
- Blog Catalogue
- Technorati
Social networking seems to be increasingly popular at them moment but social bookmarking is much more widely used, for the time being at least.
