2010, rather than earlier years, may be the definitive year for social networks.

Just as before Google there were Alta Vista, Excite and all the others, but web search really came into its own with Google, I think we are seeing something similar in the field of social networks, and I don't think the current players are showing us what these networks will eventually look like. Now that high profile figures are quitting facebook, and there is an appeal for an open distributed social network, I think we are witnessing the birth of a real revolution in this field. Or it may fizzle.
