Web-based communities

Some websites that potentially sit under the Web 2.0 umbrella have built new online social networks amongst the general public. Some of the websites run social software where people work together. Other websites reproduce several individuals' RSS feeds on one page. Other ones provide deeplinking between individual websites.

The syndication and messaging capabilities of Web 2.0 have fostered, to a greater or lesser degree, a tightly-woven social fabric among individuals. Arguably, the nature of online communities has changed in recent months and years. The meaning of these inferred changes, however, has pundits divided. Basically, ideological lines run thusly: Web 2.0 either empowers the individual and provides an outlet for the "voice of the voiceless"; or it elevates the amateur to the detriment of professionalism, expertise and clarity.
