Communities are how Linden Labs provides entry points, in Triangle of Fire, I talked about how there should be a user super-continent of the best of SL now, including its best clubs, venues and so on, that are sim size.
Well then, why not a "Community" as the Azure isles are? Why not assemble a pleasure district which has the clubs, and so on? Why, instead of scattered islands floating like corpses in the water, a "Community?"
Again, LL should facilitate this by relocating islands for free, and a government, a kind of oligarchy of the mode of renaissance Italy, be formed. The community itself could provide better entry, though that should be the common experience through the web site.
This doesn't obviate the need to end traffic/camping, but it would concentrate content that is user generated into a show case, and thus provide an entry point for outworlders looking for the best in world providers, rather than the hit or miss of self-promotion, and the increasingly clotted world of search.
It can be done, it should be done, and I think something like it must be done.
