RL business start to look elsewhere

AOL is the latest to start looking for other virtual worlds to expand their markets.
Announcing on their Blog the intention to explore other virtual worlds:-
'We've gained a lot of insight from our participation in Second Life and we're now refocusing our efforts in virtual worlds. While we have closed AOL Pointe, you will soon be seeing more of AOL products and content across the metaverse. So stay tuned to aol.com for more information about when and where!'

It leaves us wondering if Linden Labs attempts to bring commercialism into SL have failed, last week coco-cola also announced their intention of trying other virtual environments.
The stability of the grid as a whole is a main concern for residents so we have to ask why would big business stay?
