I’m not sure if this should be a widget or just appear inline, but it would be a great way of expanding the audience. You get an “Invite a friend to answer this question” so if people know somebody who may know they answer it is easy for them to invite them – maybe a box pops out with a standard message that they can then alter.
Additionally you could offer a sign up bonus of reputation if the recommended friend signs up and answers
one vote up.. good social media idea IMO . . surprised it has not been mentioned before.. or maybe it has !
agree, great addition. Qhub offers this functionality if i’m not mistaken. There when you register or go to your profile you can invite friends automatically via gmail/facebook etc etc.
