Absolutely right, my friend!
The bitcointalk forum and announcement topics of projects here are the best place, best official place to release important and official news about projects.
What's going one, future plans, both of them should officially released in the ann topics there at first.
Important questions should be addressed in the forum if it has been asked here. Not all people are joining these telegram channels and reading them one by one. It is better to read in the official thread or website. At least you don't need to join the channel.
