I was sorta left mouth agape when I read this nugget.  24/7 went and hired former Clicker, Oleg Vishnepolsky!  I used to commute with Oleg (he drove) for a while and those were some fun drives.  When he left DoubleClick, and went to work for AOL, I thought it was pretty cool.  But his recent defection from AOL to work for 24/7 is a tad surprising.
