AOL's Platform-A president Greg Coleman is leaving AOL after only a couple of months in the position, as part of big changes at AOL since Tim Armstrong replaced Randy Falco as chairman/CEO less than a month ago. Coleman's dismissal comes after Time Warner reported a 7% decline in revenues in the first quarter of 2009, which it attributed largely to decreases at the AOL publishing and filmed entertainment segments, offset partially by an increase at the networks segment.
