We’re working on Frontier now more than ever, but the cursor has shifted from this WordPress site to sites using the new tools we’re developing.
At the center of everything is a river of Frontier news that’s subscribed to all the feeds. It’s the quickest way to find out what’s new.

And there’s hellofrontier.com, which is an introduction to Frontier development in 2011.
And of course much of the info posted here is current and useful and not going anywhere.
