I have noticed on a couple of Myspace 2.0 profiles that the Last Login date bounces around. One day it will show say, 11/10/09, then a day or two later it will say that same thing, buta refresh later will update it to say 11/14/09. Then I clear my browser cache and refresh, and sometimes (not always) it will go back to the first date 11/10/09. Back and forth like that. Then a couple of day later it might go to say 11/20/09, and I clear my cache and it go back to 11/14/09 but it actually appears that they still haven't logged in since the first date 11/10/09.
Clearing my cache is unpredictable on which date it will show though after refresh. Does anyone have any suggestion why this could be happening?
