I think it really depends on the hub, and the writer. You have to sort of read between the lines a bit in a place like HubPages since many people are here for many different reasons. Some are actual writers, and some just have a few thoughts they wish to convey. Both are fine. The Internet certainly is open to that and allows for that. If you come into the shorter hub with at least some sort of understanding about the writer and the point that the writer is trying to make then that really should be the basis for your response, or how you ultimately rate it.
