I added a fork of Asaf Gartner's twitch panel at https://handmade.network/streams/live
several montsh ago ago. It is not currently synced with the streams known through being linked on projects or user profiles; it simply uses a set of twitch usernames which is whatever I thought of including back when I added it. If you do not see a stream which you think should be included, let me know and I can quickly add it.
We'll have a better system for this, including information about what streams are scheduled ahead of time, in the future.
