Firstly, I have nothing to do with 3Speak and I just use the platform to post my videos... Mostly, because it's built on/for HIVE and I like to support Web3 initiatives... That's why even when they have issues, I try to post on LBRY and not YouTube... I'm aware of the problems that both platforms have, but it's important to support the effort of people whom I know...
I don't know how development goes there, and I can't share more info on that...
The biggest conference is definitely HiveFest (https://hivefe.st/), and it will take place next week in Kuala Lumpur... There is usually YT stream from the event, so you can check it out https://www.youtube.com/hivefest
HIVE is decentralized, which means that there is no "one person to serve everyone," and people go in different directions, which means that you can (and will) hit the wall with some of them... I did many times too... lol...
I wanted to understand if something is moving forward or if we're just wasting time.
It really depends on what your expectations of HIVE are... In the end, it is a social network and the most valuable part of it is people and the community... Not talking about devs or whales, but rather about regular peeps who care about each other...
But, I do agree that we need some fresh devs, who will think outside the box and create some useful stuff on HIVE...
