I've heard that when you share GAG on Facebook, Twitter and G+, you earn 100 Xper points per each share.
Where can I share and earn the points? :p

Sharing questions on either Facebook, Twitter or google+
will provide you with 20 points, not a 100.
The 100 point bonus, is granted one time, when
following GaG on the above mentioned social media
or connecting your GaG account, with said social media.
You should be able to find the share buttons on
all questions. The buttons you're looking for is at the
bottom of the askers "details" marked with an icon/color
to let you know, which is which. ^.^0
