It's a private company, it's not an open source project. Sure enough it's built upon a huge worldwide community volunteer work. We, volunteers, have joined a successful idea based on a novel "wiki-licensed" Q&A model. 

I'm reading those meta posts as the company reaching the community asking *"What do you think about this trial ballon we're studying/launching?"*. Yes, it subverts the Q&A model which we helped to build and we do enforce on a daily basis (*"Sorry, this is not a help forum, a discussion board nor a search engine. Please, focus your question [this way] and refer to the Help Center for details."*).

I'm fine with controlled-subversion of the system to reach the core community to help conceptualize, experiment and build new stuff. What's the community participation on other channels (Blog, Podcast, Twitter, FB, G+, ...)? Very low AFAIK.

Or then, by all means, install a [<code><b>discourse</b>.stackexchange.com</code>](http://www.discourse.org/) instance, so we have a tool that's more adequate than Q&As or Chat rooms (or social tools) to organize opionionated discussions.

*Should Discourse be installed as another pet project by SE?*</sub>
