It's a private company, it's not an open source project. Sure enough it's buildbuilt 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 discourse.stackexchange.com
instance, so we have a tool that's more adequate than Q&As or Chat rooms (or social tools) to organize opionionated discussions.
There you have it!
Should Discourse be installed as another pet project by SE?
