I empathise with Blue, as someone in a band that plays stuff for money, and am very glad he posts topics like this that glean a lot of different responses.
For sure there are those who play purely for fun, and that's the other end of the spectrum. But there are enough truths in that original checklist to help anyone doing the 'internet band dating' thing.
Talking of that, I got my current gig on personal recommendation. In the previous year, six start-ups failed - I left three, three left me - which has made me think that there's still no substitute for making connections in real life.
