GMail invites used to be hard to acquire. I remember people selling GMail invites for $100+ on eBay and people were happily buying.
Well now GMail is a public service, no invitation necessary. So now what are people buying?
Pre-registered GMail addresses!
Yep. People are paying for "hot" "rare" "supercool" GMail addresses on eBay.
Check
this one out. $50+ for a free GMail address?
That one is for wii.will.wii.will.rock.ya@gmail.com. GMail ignores periods in addresses, so somebody went and registered wiiwillwiiwillrockya as a GMail address and someone actually wants to buy it from them!
That's just weird.
