Descriptions are meant to be read, they give a player or place basic atmosphere.

One thing about room descriptions, however, is that it can make a tavern for example, feel like a much larger envirorment for rp instead of just a closet where you can almost feel what else is in there. It can make people try to get attention as well, since there may as well be someone back in a corner, or maybe someone that couldn't see your character entering.

Or maybe it's a street, or a flight deck, miles long, could a character see someone on the opposite side? Not in most cases, or that character has telescopic vision, yet this kind of stuff seems to be sacrificed, maybe your character should have to come up with something to attract attention. Not too much, but something of interest, at least.

This is an underused part of descriptions, I think most people keep it general so they look like they know what they are doing, and I'm not saying everyone has to be perfect, but they should be able to have a basic idea of what is going on. While MU*s are based on imagination, it is also based on constraints of the descriptions and those of the other players.
