I don't care if companies try to insult me with their pricing (I'll gladly buy the "hobbyist tier" if that's what I need), but please, just publish pricing.
I hate when pricing sheets say "Call us for pricing" - just tell me outright, are you charging $5 a seat or $500 a seat? I'm not going to call or email to find out, I always assume that "if you have to ask, you can't afford it".
