Oh, I was just dumping the link because I know students (and advisors) are looking for tight studies that students can replicate. When a minor publication could come out of a study well executed, all the better.

I think the authors gave a lot away about their own preoccupations. Most people I know engage with the internet quite gregariously. Here in the south-east of UK people get to know each other and each others families. Friendships form very quickly.

There is a large group of people who are scared of the internet though. Usually they are older. They might also be leading a double life and be fairly desperate to conceal their off line life from their employers (even thought their lives might be quite humdrum.)

I've just added a link to Typelyzer. As far as I can see, but obviously I have a selection bias, most bloggers are INTJ (apparently it dominates psychology here too) and IST*. There are some ESTP about too.

That seems to support the idea of introverts being online but you wouldn't think so to see the social life.

PS Being anonymous online is not done at all. Authenticity is important. People want to know whose voice they are listening to. Young people seem to have well developed abilities to check views from multiple sources, to discern provenance and to form a multi-layered multi-perspective. Older people are particularly locked into ideas of authority and look for information that is backed by authority (rather than argument, facts and honest disclosure of interests).

Enough! Have a good trip!
