Have you by any chance checked the forum of dYdX (img1)? The topics there are very informative. Some are pretty technical, but it is cool to see they have great activity there.
I want to break it down by per category where dYdX is currently active in.
203.5K Followers, 2,631 tweets. Many tweets and following their timeline will keep you updated on all the developments that are relevant for (retail) investors. The average view per post hoovers around 10k.
Discord
31,759 members, 2,973 online. Good ratio and member activity. This is mainly used to chat with other traders.
YouTube
11 video's and 3,390 subscribers. Not that impressive, but in the video there are helpful tutorials.
No Medium, but Reddit. Both will do, but somehow I feel Medium has a more professional character, but that's just my opinion. Reddit shows a decent activity for dYdX with some relevant posts.
6,952 followers. They barely post here, but you can find sufficient info and, of course, you find their fully doxxed team. Job options are up-to-date and posted on LinkedIn too.
Conclusion I give five stars, but I do think dYdX can get more out of their YouTube-channel and maybe post the highlights that they Tweet on Twitter on their LinkedIn. It's never bad to promote yourself without losing the confidence of your targeted audience. Show Less
