I don't know where else to put this, so I'm just going to put my thwack feedback right here.
1) On my profile's Activity page, the timestamp for the activities is in milliseconds since epoch. If you hover over the timestamp you do see a human-readable version. I always prided myself on being geeky, but reading timestamps instead of regular dates is a little beyond me. (And to think, I thought those binary watches were too time-consuming to interpret!)
2) To make it a little less obnoxious, you should set the size limit for uploaded files from 3000 KB to 3072 KB. That will result in the "Maximum file size" message being "3 MB" instead of "2.9296875 MB" (3000/1024 = 2.9296875).
Thanks for making a great user community!
