Instead of allowing these social sites to drain your member's activity we need to be more smart and "use" these sites to our own benefit. It would be awesome if the Facebook and Twitter integration that XenForo offers could do this by default:
1. Allow people to post on their Facebook wall about a new thread that they are creating so when they are creating a thread a checkbox labeled "Post on Facebook" should be displayed.
2. Allow people to also post their status on Twitter.
3. Allow people to share on Facebook/Twitter whenever they get a new trophy!
At least one of these (#2 specifically) was considered by @Kier since the first days:
We're keeping it at 140 chars so it can be automatically sent to Twitter when we get around to coding that particular implementation.
There is currently an add-on by @Chris D that does everything described here: Social Connect. However his add-on requires a second association with Facebook/Twitter in order to work (see my question and the answer by Chris). Why? Long history short because XF's Facebook/Twitter integration doesn't asks for the required permissions.
And because of the limitation explained above I think that this should be a core feature, a must have!
