I hate the the 80 character limit. I never follow it, though using 2 char instead of 4 char indentation might help. The main reason I hate it is pretty simple: I think it encourages using cryptically named variables. I find that using properly descriptive naming often leaves lines around 90 to 100 chars, particularly with 4-space indents and several arguments or a chained call. I also don't find the suggested practice of implied multi-line via unclosed parens leads to good readability in many cases. That said, I agree there should be some limit. My usual practice is to set it at 120 chars, though I find it rare for a line to exceed 90 to 100 chars.
