So, it seems like they are trying again today. SpaceX's site does not have a link for a youtube feed yet, but their webpage indicates they will post one...

So, on Tuesday, I used the Labpadre live feed only in the background to monitor audio, as live feeds on other sites was continuous talk-talk-talk for hours. LabPadre was silent most of the time, getting more active once there were actual signs of something happening soon.
Then I begin using the NASAspaceflight (NSF) feed as things seems to be closer to happening. Such as the NASA WB-57 weather plane, and indications of fueling by visible signs of vapor.
Here's NSF's live feed for today:
The SpaceX feed went "live" only about 5 minutes before T-0. THAT is the one to watch, if you only watch one. Because of course they have various close-up cameras and the last few seconds showed an onboard base view looking down at the engines, and also two "Cineroc view" cameras onboard Starship looking down at the lower fins. Those two cameras will be VERY useful to see how well the belly-flop descent control system works out.
I had a second monitor going, so I had the SpaceX feed on the big monitor, and the NSF feed on the smaller monitor. I also had Everyday Astronaut's feed going, partly visible on the second monitor, so I could click between NSF and EA's feeds for different views. But those views were probably only going to be useful for a short time during launch, and for the last kilometer or so for landing (most critical phase), their cameras are miles away and did not seem optimal for high quality images. The rest of the flight, the best views would be the SpaceX feed, due to the onboard cameras. Also for the transition/landing, I expect SpaceX to have the best external camera views too (though with the onboard cameras, I'm not sure how much emphasis they are putting into great quality external cameras to zoom in to follow it all the way up).
I had the day off from work yesterday, so had the time to monitor what was going on, and watch. Today, I have to be at work before 2 PM, so I won't get to see it live.
