Just dropping in quickly to say: yes!
The Flotilla project is still very much a going concern, we've had meetings about it recently, and several of us have got long todo lists with "make Flotilla awesome" just repeated over and over and over.
We've recently had two new hires, Emma and Lydia who are helping us technical-minded folk (who get too hung up on details) refine Flotilla and continue to improve the software and documentation.
If you follow #BilgeTank, you'll see us mention it from time to time. See for a sneak peek at some of the stuff we've been working on; https://youtu.be/HaXqAjumftc?t=385
I also have a very rough prototype for a new module that I want to get off the ground as soon as possible. Basically: stay tuned :D

The very bleeding-edge and usually broken Rockpool is here: http://flotil.la/rockpool-edge/
And if you don't hear from us on the forums, it's probably because we're stupendously busy working on it :D
