And the Beta goes Public07 Oct 2014, by Artur Malabarba.
The site goes well and the curtains are raised. The Emacs.StackExchange beta has left the privacy of its dressing room and ventures onto the public stage. Even if you have nothing in your mind to ask, go pay it a visit and have a browse through the questions. The quality of content is impressive, and you’re sure to learn something of interest.
I’ve already brought here several lessons I would never have learnt if not for the beta. Smart Dired, Longlines mode, and Aggressive Auto-indentation are now essential parts of my init file. Of course, I’ll keep bringing more, they come up faster than I can write about them.
Not to mention, the community is friendly and intelligent. Not that it’s any surprise in the Emacs ecosystem.
