Slight inconsistency with birthdate field

[LB]

The birthdate field looks like it wants yyyy-mm-dd format:

However, it's not possible to type dashes, and using the date selector fills in using mm/dd/yyyy format. My age shows correctly in my profile, so I guess the placeholder text is just outdated.

Also in the topic listing, I move my mouse to the left white space so I can read the topic names, but it crosses over an avatar temporarily and suddenly a usercard is permanently obscuring topic names, and I have to move my mouse all over the place until it goes away (it stays forever if I leave my mouse in the white area on the left)

Mm, the user cards are new, so it could probably use some polish.
