Favourite sites? ebay.com which I liken to a giant worldwide flea market. It's the world's biggest auction site. The items range in price from 10 cents up to 10m dollars and it has more than one and a half million items for auction. You can search for anything. As a joke my wife searched for antique Argentinian barbed wire and they had it. It's a phenomenal site, albeit that 99% is rubbish.
Last online purchase? I buy quite a lot online. The last thing was a vintage movie poster of Rasputin which I bought from a gallery in New York. Everything arrived perfectly.
Most recent technological faux pas? I needed to make a small change to the site but I couldn't get hold of our programmers. So I thought I'd try my HTML skills. The result was that I took our site off the air for three days for netscape users, until someone pointed out that the site wasn't available on that browser.
Main news sources on the web? The news feed I use most often is Yahoo and Altavista. It delivers the sort of news I need, such as developments in legal services and changes in the law.
Most persistent spam emailer? I don't get spam. I've got 2,500 emails in my outlook at the moment and not one is spam.
Time spent on the web? It's on from the moment I arrive at work until the moment I leave.
Next boo.com? I think it's going to be any site that places heavy reliance on WAP technology. Unless the information being delivered by WAP is simple, such as share prices or football scores, I can't see how WAP can deliver information in a manageable form.
Least useful site on web? Any site that asks you to fill in a form before you go any further. I immediately log off. Nobody asks you to fill in a questionnaire in a shop before you can go further. It's absurd.
Most useful site? Google - it's difficult to beat as a research tool.
Which screensaver do you use? I'm having a bespoke screensaver built at the moment. It's a little monk walking around the screen with a bag of posters. He pastes them on the screen like billboards - they are adverts for our website.
Most irritating things about the web? The noise of the modem when you dial up from home.
Do you bother with old media? Yes - I'm a media junkie. I buy the Times and the London Evening Standard every day, the Guardian and Sunday Business at the weekend.
