Rob Conley put up a good post about the value of terse dungeon descriptions, referencing my own post from yesterday.
My comments yesterday about the non-publishable nature of Felltower as written might be easy to interpret, though. Here is what I commented on Rob's post:
"To be clear, I'm not saying you can't write a terse but effective and publishable dungeon. I'm saying you can't just grab up notes meant for a GM who is making stuff up on the fly and noting down only what he doesn't want to forget and publish that. Like Castle Greyhawk, if I handed someone else Felltower it would be a mess to try to run. I could publish a terse version, but it would need to be re-written since it's not in any kind of state conducive to other people running it."
Basically, I was talking about my dungeon. Also, I'd note that if I did make Felltower into a publishable dungeon, it would either be a) verbose, or b) run very differently in the hands of someone else. Not that b) is a bad thing, just that it's not the same thing as "really running Felltower" would be.
