I spent a little time reading this Pew Internet survey on Twitter and Status Updating.
It feels strange to be close to the edge of this classification:
Twitter and similar services have been most avidly embraced by young adults. Nearly one in five (19%) online adults ages 18 and 24 have ever used Twitter and its ilk, as have 20% of online adults 25 to 34. Use of these services drops off steadily after age 35 with 10% of 35 to 44 year olds and 5% of 45 to 54 year olds using Twitter. The decline is even more stark among older internet users; 4% of 55-64 year olds and 2% of those 65 and older use Twitter.
I think the key trends are that Twitter users are racially and ethnically more diverse than the population at large, and that they are more likely to be using wireless devices and smartphones. Of course, as the report suggests, this may be due predominantly as a result of the relative youth of the Twitter user. But I think it’s more than that.
I think we need to recognise that Twitter lowers barriers to entry, reduces the cost of participation. Which means more people get enfranchised, are able to take part. Twitter is not necessarily about high speed internet connections and industrial strength desktops. I think there is a class of person who is attracted to Twitter just because of that. Nothing to do with age.
