They should rarely post on public forums, as there is no equals for exchange. And there is no new quality experimental/practical researches to discuss between them. So they are stuck in own speculative types understanding and are doubtful to develop significantly with the existing.
To mess with noobs or where those communicate is mainly an entertainment (for noobs exist articles, books, etc). 99% of messages on typology sites are made by random people without minimum competence in typology. At best they read popular beginners texts and did tests, in case talk for significant time there. 5% of them mb read Jung's book too. You'll not find principally different on Jung types related sites, besides in a number of incompetent messages made by ones who understand a few in practice and trust blindly to doubtful ideas.
New wave of Jung typology may appear when IQ-alike tests will be developed for every of 4 functions. Or mb objective measurements for the same, did on good level. Mb researches of physical reactions in communications in different IR. For this is good to have academic education and resources. It's not the level of random noobs and doubtful for speculative practitioneers. Check what resources and education levels are used to make significant researches in psychology/physiology. As to develop a variant of IQ test. It's close complexity to do new in Jung typology.
