A few interesting points:

the average time between any two tweets from the same user is exactly 24 hours.

i.e. people use Twitter every day.

The rate of new user acquisition has plateaued at around 8 million per month.

Wow, only 8m new users per month. That's gotta hurt.

We know that Twitter has 50 million registered users

OK, small user base then.

View on HN

the problem with the user base seems more likely to be that you can ignore almost 75% of all users due to no activity

Not exactly - twitter, unlike facebook, is asymmetric, so you expect a large percentage of users who are just listening. That doesn't mean you can ignore them - they are the audience.

you're right about the asymmetry, but let's not pretend that 75% of 60M are actively listening to anyone...

I would be stunned if that number was higher than 10%
