Today, a "proposal" to create a Joomla Hub on Stackexchange has been generating some interest in the Joomla Community. Having a Q&A Hub on Stackexchange, which is probably by far the most popular platform for Q&A sites, would be a good thing for Joomla.
But we aren't there yet. Before we can turn this "wishfull thinking" into reality (Or a Beta-version of that reality) the proposal is in need of people willing to "Commit". Commiting basically means promising that you would use the hub for 3 months while it's in beta, and answer (at least) 10 questions.
Before the hub can go into beta, it needs a certain number of these "commits". We're only at 30% of the goal and could use a lot more commits. So if a Joomla Hub on Stackexchange is something you'd like to see (and use), find your way to Area51 on Stackexchange and "commit" yourself to support the Hub!
