I agree with most of the above. But we need a different approach. Apart from python, keeping up with plugins is my problem.
For me, I've been on here for a while and the forum is a great source of help when wanting to tackle a problem. However with a year and a half away building a new house, I now feel that there are gaps in my knowledge (eg homebridge etc) that were developed/explored/extended while I was "away". I know I can catch up but some of the threads are hundreds of posts long and resolving an error without reading the whole lot takes time.
I suspect that for new people coming in the learning curve is high, and could be daunting for the less able.
What I feel would be useful would be some form of organisation and brief instructions on all of the current plugins. Many of the more experienced developers do this in their forum pages, but a central referenced library would make things easier for new people coming in. Then following each a troubleshooting of common errors.
I think its a big ask for Matt and Jay to look at this.
Perhaps its a case of making a list of everything that needs doing, volunteering to write sections, and then Matt, Jay and a small team editing it all together?
