This latter point contains an interesting sub-plot, which is that the proportion of respondents 15 - 24 who claimed to have a profile on a social networking site actually fell from 55% to 50%. Maybe they're shifting to anti-social networking, from Bebo to ASBO, as it were. Or maybe they see the herd of more mature users invading their space and fear being bombarded by ads for laser corrective surgery or invitations to become fans of hip replacement surgery. Churn, baby, churn.
The release of these findings today is ironic to me, coming on the same day as I received a Facebook friend request from a relative in Texas in her mid-60's, and also as ITV, the embarrassing uncle in mid-life crisis desperately in search of a way to remain relevant, gave up the ghost on Friends Reunited. But only after paying a £55m earn-out earlier this year - ouch.
