Just because many people are not using something, it doesn't mean demand for that something is high. Often, it's the other way around - if many people are not using something, it's usually due to low demand (at this price).

What price? Time, effort, attention, opportunity costs, etc.

I think it's barrier to entry. It must be very frustrating to join Twitter today, see people with thousands of followers and not having any.

Most non-famous people I know who joined Twitter recently follow 50-100 people and have a handful of followers (who know them in real life). They get bored quickly and stop using it.

But those people still have an account...the article is about people who haven't even tried Twitter.

I joined Twitter several years ago but I still had the same experience.

Actually, that's exactly what it means. Demand = consumption.

Opportunity for growth and growth are not the same thing. I think Twitter has opportunity for growth, but that's not to say they will definitely execute on it.
