The internet is very much a social world, built around web 2.0 platforms. Social bookmarking takes regular bookmarking to a new social level. Users can bookmark their information, but then post it using a link and thereby share it within their own online communities. The site is still bookmarked, just as before, but it is available to be seen, read and shared by an online network who is interested in the same types of information. The online community builds links, tags and shares blogs, articles or other interesting pages that are within the niche of the group. Here are the top ten social bookmarking communities.
