It's something vital on the Wordpress sites I run, and on the vBulletin sites it brings in traffic.
Social Posting / Sharing / call it what you want. We have the manual sharing here already in NodeBB and that's great, but I want to be able to have it broadcast out when a new topic goes up. Yeah, there's always the risk of a rogue spammer but that's what delete buttons and spam protection are for.
Twitter / FB / Google+ are the big three. I know we talked about IFTTT in the past and it won't be able to pull the threads directly as a part of a recipe. But maybe we can use it to read the RSS and then post accordingly? I'm going to screw around later tonight and see what I can come up with.
Of course, if this was just a plug-in for us lazy shitheads that would be amazing! But a little hard work goes a long way. BBL.
