Here's an idea for a L$ money sink!!!
Linden Labs could go into the business of renting out land that is eventually destined for the auction block!
There's a lot of land available in SL, and some of it belongs to people who no longer play. That land is eventually reclaimed and auctioned off by Linden Labs.
A nice money sink might be to allow short term leases on Governor Linden's land, with payment in L$.
We're talking about land that people have stopped paying tier on, but has not yet been purchased by a new owner.
--------------------------
Alternate idea:
A city sim owned by LL, nicely designed and maintained, with more permanent rentable space by Governor Linden.
Ok - there we go - I've spit out a hair-brained idea....I expect to be chewed up and spit out now.
