I loved this article! I tried various social nets when they came out, and after a couple of months ditched them all for the reasons stated here. As Alan says, "it's just not me".
And as for "having" to be a member of social networking site in order to meet the expectations of employers? I've never heard anything so ridiculous. Any employer who wouldn't hire you because you don't belong to a social network is not worth working for, and moreover, is an employer to avoid like the plague. I'm sure there are employers who consider such things, and those are precisely the employers you should make a point of avoiding. If you, as a professional, need to have an online presence as part of your work, then there are plenty of other ways to create that presence ... ways that don't compromise your privacy, your control over your content, or your principles. Create a website or websites. Create a blog. Create photo albums. Write articles. Write reviews. Write comments to articles. But only join a social network if that's the sort of thing you enjoy doing for your own reasons.
