@kev the question is, is this unusual? Just under half the world’s population is going to be over the age of 40. Probably about a quarter are going to be under 20, but you also wouldn’t expect the vast majority of that age group to be on social media. So, I suppose the only stand out data here is the relatively disproportionate number of people in the 21-30 category.

Although, from my memory, that’s fairly similar to Twitter and Facebook.
