I know it's a really picky take, but I resent the implication that I should want to keep my personal files mixed in at the same level of the file hierarchy as all my applications' random settings, cached data, and temporary garbage. Documents, Music, Videos, Projects, .config, .cache, SelfishAppName, OtherSelfishAppName...
It bothered me when Microsoft started doing it in Win95, and it still bothers me in Linux. Especially when software acts surprised (or occasionally indignant) that I don't keep all my files in those directories. I have lost small bits of my own work over the years by forgetting to back up things that recalcitrant software refused to store anywhere else.
But I am amused that this is the same name that I use at the top of my own storage hierarchy for self-made things.
