If you look at my signature, you can see that I'm a male Kelly myself. (As to why I'm on a pregnancy board, I saw this thread on the "Recent Discussions" list; the main thing I visit Mothering for is on the (anti-) circumcision board to share my thoughts on intactness.) I do get the occasional "Isn't that a girl's name?" or the wrong salutation, but other than that I've worn it well and think it's a great name for a boy! I also agree with others that it may be easier than when we were kids, since Kelly has dropped in popularity for girls and with all the popular names being used both ways kids these days tend to be less harsh with unisex names in general.
The regional thing is another interesting point I've noticed from my observations (and from the SSA state-by-state popularity lists) - surprisingly those in the more conservative areas of the country tend to use names both ways more often, with the Northeast showing the greatest phobia against cross-gender names for boys.
