Unfinished Cogitation on Things
Sometimes I think it would be easier, in a lot of respects, for LL to make another, updated, Second Life that would allow for the unpredictable (3 years ago) things that people have done.* I think they constantly have to stick their fingers in the dike. Things quickly scale up into bizarre, lop-sided forms.

As an example, take avatar attachments. I believe Washu Z was the first person to make prim hair, which has made a great deal of difference in the way avatars look. Before prim hair there was only Linden hair (I still have Linden hair as I don't really care** about hair). Prim hair became incredibly complex, prim-heavy, and lagarrific. Prim hairstylists often didn't seem to get the idea that computers have to render the geometry of all these prims, and would make bazillion-prim hair using twisted tori - by all accounts the most difficult of shapes to be rendered. When flexi-prims came in I thought perhaps it was LL's way to get rid of those old-style laggy torus hairdos as the torus can't be made floopy...

*On the other hand, you could argue that if they did it would only be a equaliser for the things already done, and that new things might soon render the updated version outdated.
**In real life I was able to grow really beautiful hair out of my scalp up until the golden blonde grew dim. I'd be stopped in the street by people who would say, "You have beautiful hair!" I never cared about it, though, and just used to either have it cut very short or grow it very long as "I leave it alone and it leaves me alone."
