The dates in the player profile 'most recent games' don't localize the date format and use the US format. mm/dd/yy isn't very nice for those of us outside the US.

This is low priority, but some of us have strong opinions about using mm/dd/yy.

(Also, this website has terrible trouble doing anything. I think there must be two machines serving and one of them is completely borked since every page request yields a 503 error.)
