Extreme Sharing Networks: Everyone is An Expert at Something

The quote, "Everybody is an expert at something, and can contribute in meaningful ways", for me, defines the pull towards extreme sharing networks. Extreme sharing networks exist as a community, where the main focus is helping other members out. Message boards for sharing sites like Torrentpond and eMule act as a vector where all members can "meet" and share information with one another.
While investigating these extremes sharing networks it got me thinking about a sort of sub-group of sharing networks. One which I have come across in recent months is called Tinker. Tinker is a network created by Glam Media, a vertical content network, which offers an extreme sharing and combining of social networking sites. Their motto is "Stay on top of the buzz and create your own." With Tinker you can easily create or follow an event stream by typing a keyword into an event stream. An event stream could be anything from the Oscars to the ipad release. Tinker will pull up facebook status' as well as tweets that have anything to do with your specific event stream keyword. When you post a comment, tweet or status it will also update all of your other social networks that you have linked to your Tinker account.
The revolution of these extreme social sharing networks seem to be relentless in their growth and popularity. Networks such as Tinker seem to be as extreme as I can imagine, but it makes me think... what could possibly be next? Picture status'? Video status'? I think those may be a tad bit intrusive for my taste, but I wouldn't doubt their appearance once the community of extreme social networking sites becomes bored of regular old 'text' updates...
