I never was an early adopter. After 13 years or more on the web, I still write my HTML by hand, and until this moment I haven't had a blog --- until six months ago, I had never even posted to one. In the nineties I was the web responsible for my university department, and since then I've written up popular lectures and film reviews for my home page; and the web is something I use extensively for work. But something in me has resisted its more popular forms.
Maybe it's particle-physicist snobbery: we invented the thing, and now it's completely out of our hands, and often contrary to our values. Or maybe it's that, being an opinionated person, I've been afraid of ending up as one more ranting guy at a keyboard. But in any case, I started posting to some friends' blogs a while back, and the sky did not fall in. So it seems like it's time to give this a try for myself.
As for the title, taking things seriously is what physicists do, and taking things seriously is something I've been doing, to the occasional dismay of my friends, all my life. I hope it doesn't exclude having a sense of humour, but that's for others to judge.
