Suddenly there is a plethora of gmail invites. Somone on Orkut astutely observed that it is like the stock market. The balancing act of supply and demand is amazing to watch and it's all documented on ebay. On Monday accounts were still fetching up to $200. By Wednesday they were dropping to $20, and today they seem to be plummeting further.
I gave a few of mine to some friends on Orkut. And I've looked on gmailswap.com but so far nothing quite clicked with me. So, I just gave one to a worthy soul, as facilitated by Jonas' "Do Some Good" idea.
