An hour is pretty good for presenting some stuff to some people who are there to absorb some information: for example, I went to a very good Co-op one a couple of years ago: in an hour a bunch of people passed on a lot of useful experience.Top Dog said:sovietpop is right about the meeting length problem. Nothing can be accomplished in under an hour... these sort of meetings can be no more than showcase style events.
But if you want the full-and-frank-discussion, then you're pretty much guaranteed to get a few people stating their point at interminable length, thus taking up most of an hour before it even begins.
Though, that said, utilising better methods than face-to-face meetings for such long discussions will tend to reduce the impact of the interminables; use a short meeting for introductions, "we're about this and not really that", "here's the current thinking ..." or whatever.
I suppose if you were expecting to have a long meeting you could have it in the pub next door - at least, if no-one took it on themselves to - oh, wait, they did.
