Great work Tanaike. Very interesting.
I think the comment I've seen about Stack Overflow being intimidating for 'citizen developers' is very true, and most likely puts people with beginner questions off. Ironically the pedantry there is generally not from other Apps Scripters who actually might be able to answer the question, but is a depressing feature of Stack Overflow policeman nowadays. Someone else mentioned on this thread that they've given up stack overflow - and I think many of us have.
I still miss the Google+ group we used to have - it was a much friendlier place, and because it was an Apps Script community, you were more likely to get a good answer, and you'd be more likely to want to give one if you could help.
Thanks to all on this group who give their time to help out.
