Lack of interest Ability to have social media buttons underneath avatar

Hi guys,

It'd be great to have an add-on whereby a user can add their Twitter/Facebook/Google+ link to their profile and for social media buttons to display under a user's avatar picture inside a post.

I have looked around for an add-on but haven't been able to find one. Apologies if there is one already! If there is, can somebody point me in the right direction please?

Thank you.
