If you're trading it's not pointless, and I find it fun rather than annoying I check much more than every hour if I'm thinking about making a trade. At the moment if I'm working on the computer anyway I'll be checking almost constantly. If there's no potential trades, I might only bother once or twice per day, or less depending on what I'm doing.
