harry works around people that pine for vanity usernames. vanity = big deal in those circles. who knows why. not bad in itself.
places like foursquare, people know people at twitter. if your outside the valley twitter won't even help you when the autosuspender mistakenly pops your account but valley/connected people call an investor or executive and get their vanity handle in hours. seen it happen twice.
it's all who you know and never forget it. when i dealt with twitter support as a normal the disparity between insider service and official was pretty amazing. they are the worst of the valley backscratchers.
bet they would have taken @n if the right person called. what would you do, sue?
