But it’s not just that Twitter is small and unprofitable. The truth is that few people here in the States actually use the thing. The social network remains a niche product, beloved by journalists, celebrities, and a hard core of miscellaneous obsessive users — but few others.
Unlike Facebook, it’s not a ubiquitous online utility, and you’re not going to find grandma on there.
That’s part of why I actually prefer Twitter. But the problem is that almost nobody I know in real life is on it, or they started accounts and abandoned them.
