I took a break from open-source for two years in 2014. However the last 2 years has seen a lot of updates. The updates so far has been to the bevry ecosystem, our patreon roadmap talks about some of the progress there. Some plugins are now being updated to make use of this. And there will be a release of DocPad soon to do the same - it's done, just needs more extensive testing.
The announcements and updates channels on our slack will show a lot of activity over the past 2 years.
However, feel free to use whatever you want. None are perfect. And I still use DocPad for things today as it is often still the best tool for certain tasks, and will only get better. There are some enterprise people still using it everyday for years.
However now there is also a plethora of alternative tools for alternative and similar use cases too. So if they are better, go for it.
