When I was at SLCC I had a moment where friends insisted I meet Philip Linden. During that very short conversation he said something that I believe is significant and does not appear to be getting much attention. I don't actually remember if Philip mentioned the issue in his talk or if if just came up in conversation, but while we are thinking about changes to SL that may or may not happen in 2011, I do think along with mesh LL is going to limit the number of prims avatars can wear.
Here is what I wrote based on my conversation with Philip in August,
At the "Avatar Ball" I said to Philip Linden "What scares me is avatar limits." His response was "You should be scared." Then he launched into a long discussion of region prim limits and the impact of not limiting prims/scripts for avatars. In the same breath he reiterated "But I am giving you mesh." So, there you have it.
As I have said a billionty times, I am not a technical person so I am not sure what avatar limits mean, but Philip talked about the load avatars wearing a lot of prims place on the servers. He said that back when they were creating Second Life they made a mistake when they limited the number of prim that could be rezzed in a sim but did not limit the number of prims avatars could wear. This is the problem Philip said LL needs to correct and I do think we should expect to see limits in the future.
If and when avatar limits are imposed there will be repercussions for people who like to load up their avatars with attachments. Fashionistas? Furries? Robots? Things might be changing.
