There's loads going on, but this is by far the worst place to keep abreast of developments.
The Telegram channels are the most active.
This is a weekly roundup - https://www.youtube.com/channel/UCnsSiqyb0PuQkqT4v8Xjugw

And there's plenty more out there. This thread has always been weirdly dead compared to elsewhere.
thanks @gentlemand I didn't realize there was a NEM youtube page. I will go get up to speed on things. I'll see if I can find one on COMSA. I am keen to see NEM working in the exchange space. I was harvesting for a while but when you only have 10,000 NEM's and the volume of NEM daily transactions being under 1million most days I barely harvest 6 in three months... hoping going on as I find the whole Proof of Importance idea interesting.
There is a Youtube channel named "NEM Inside" that covers NEM stuff and news weekly.
I think it is not an official channel but the host Alexandra is doing a very good job and keeps one up to date about NEM topics and development. She has covered Catapult and Comsa in recent episodes.
