Back in the times of Geocities, everyone's site was unique(ly ugly). Today, everyone's facebook page looks exactly the same. Geez, and you wonder why rate-of-use will probably decline over time?

Facebook et al. will not be the end of connecting with people online. Now that everyone's been pressed into a one-size-fits-all and the lowest common denominator has been found (satisfying your curiosity what your hs buddies are up to, who got fatter last year etc.), the game will start anew for the new shiny thing - connecting people while at the same time bringing out their best sides.
