Joe Public will tolerate mediocrity when it comes to most other band members. Again, IMO.[/quote]
I'm 100% with WoT here. You can always hide or turn down a rhythm guitarist.
It depends on the genre too. It's worse with covers bands and some genres lend themselves more to performance than technical ability. A folk band or a loud rock band can have slightly wayward vocals but with soul music it doesn't work. I try to only work with good singers and drummers personally. I'm not afriad of working with musicians who are worse than me but generally I try and work with people who are of a similar or higher standard so I can push myself.
