Most people (and competitors) underappreciate how well Elon manages requirements over Twitter.

If you want to know why he selected the features for the Cybertruck, go back 1 year when he asked the desired features on Twitter. It's crazy how many of those small looking features (like a bed for normal sized / tall people, lighting in the back) were included in all models.

Also he's averaged about 2 tweets a day over the hols and it's often less. It's probably not a huge amount of time.

Considering the amount of publicity he gets from Twitter, they can definitely be considered productive.

I wouldn’t count it as productive when the outcome is he has to spend time in court explaining himself later. I’d venture to guess the time spends directing his employees is whether all the productivity happens.
