Something like we have in Xenforo. A block add on which can add these buttons will be nice. Not sure if it has been covered before some option to display our profile pages will also be a nice addition. Got reminded of this when saw the social share buttons. I guess most of them are blocked by AdBlock Plus these days.
I'm not entirely sure what you mean... :-\
Isn't it the same as the social links addon posted by Spuds?
That will share only forum post, right ? I was just wondering if we can share the forum home page or +1 it.
Also as in WordPress, some add on to show our FB, G+, Twitter, YouTube etc profile pages.
