What is your birthsign? How about your character's? Do you even use birthsigns? In Oblivion you have to choose one of course, but you can make a safe choice that doesn't do much, or you can be more adventurous and take on a curse. How about your followers? Oblivion NPCs don't have birthsigns, but of course you can add them. Skyrim doesn't have birthsigns - standing stones are not the same, you can no more change your birthsign as you can change your birthday. So there are mods to add birthsigns, and anyway it's easy to do yourself, even just through role play. So, do you? Declare yourselves!
I'll start.
Lena Wolf was born under the Apprentice, and she carries that in Skyrim as well (personal start mod). That's +100 magicka and 100% weakness to magic.
I give birthsigns to my companions as well. Hauk was born under the Lord, for example.
My own birthsign is the Lady (infatuation with shoes and chocolate).
How about you?
