I was using them until this Feb. when I crashed the bike. I found the position quite convenient when riding on the tops, a bit awkward from the drops. I think for commuting they are a better position than downtube shifters or bar-ends. Of course, if you ask a "roadie" they'll tell you you'll impale yourself on them in a crash, but if you're flying hard enough into the stem to impale yourself on a shifter, you're going to get hurt by something anyway.
