For instance, I would love to be in YC- But just like many older (30+) folks, I have a family and simply cannot move to SF. The 'move to SF' restriction is the one thing I hate about YC- Its also why I think some competing incubators are picking up steam, who focus on global teams.
This may be disagreed upon- But I truly feel the 'move to SF' restriction is almost prejudicial against older folks. I get there is immense value in being in the valley (I just moved from SF), but I just dont think thats a reason not to find a way the system couldn't work either remotely or satellite based.
