@developer fact is, the product needs marketing as much as new developers. There could be some videos on the main site highlighting the UI features because there are quite a few useful tricks that are not apparent for new users - to be fair, this is an issue for a tool like a phone that has no place on the screen for extended help, however there is a wealth of news articles, third party videos and user base that compensates this for Android while there is not much for UT. I have browsed a bit the videos on Youtube and found a (too big) number of basic videos giving only basic introduction so your impression may be biased too much on 'early adopters'. Using a supported phone (Volla, Fairphone, Brax now it seems) makes a difference in ease of use not having to delve too much into custom roms.
