I completely understand the desire for peace of mind and the madness of anxiety, but I still feel that a phone call should be a last resort -- for example, once a slew of rejections and acceptances have gone out, and you haven't heard anything. Not this early in the season, with one or two acceptances on the board. Obviously, more responses are coming. What benefit is there to getting a general answer like "responses will be out in February"? Anyway, that information can usually be gleaned from past years.
One phone call might not make a big deal, but you also might not be the only one calling/emailing. These people are usually overworked and swamped with tasks, especially at this time of year. I don't see the need in interrupting them with a phone call, even if it's just a minute, just because the waiting is painful. I agree with whoever mentioned upthread that patience is a sign of maturity.
If you felt the call wasn't a big deal to you or them, OK. Cool. But personally, I don't think I will share any more info on the boards, at least not early info like that. I didn't really think of the consequences; I just thought it would provide helpful info, not make people more stressed.
You can't control what people will do or how they'll react, so sometimes the best course of action is no action.
