portfast should only be enabled on ports that are connected to end systems (Pc's / Servers/ etc). No switches should be connected to these ports, since STP does not run on them. Also to safe guard in case of loops (bpdu-guard) should be enabled in conjunction with portfast. (to your question "switches/bridges" would the only place port fast would be enabled)
STP is still running on portfast-enabled ports. Portfast only skips listening and learning phase, the port goes to forwarding state immediately. The latest CatOS even brings possibility to use portfast on trunk ports (but some people don't recommend it).
But definitely it should be enabled on host ports (connecting servers, user PCs, printers, etc., to switches). BPDU guard is also a good idea on these ports.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
