I don't like heroku
I think it's pretty trivial to see where this is leading too... :)
platforms like heroku make me want to pull my hair out -- not knowing things like cpu/mem usage, being able to use tools like netstat/lsof, etc.... this is why these #PAAS offering will eventually die out -- they simply don't give you what you need to scale appropriately -- now don't get me wrong, give me a barebones ec2 instance (or 200 of them) and I'll be good but this PAAS stuff -- not digging it at all
