I just found a bucket in my S3 collection that had 40 gigabytes of crap I put there six years ago. I had no idea it was all there. Lots of high rez photos I used to test FlickrFan, a software snack from long ago. This is stuff that I'll never ever get back to even if I live to be 150.
What's amazing about it is that my AWS bill for this account is about $30 a month. There are probably a lot of these archives buried in little nooks and crannies up there. Never to be looked at by anyone. :-)
