OK, I have another vice. At the beginning of last week I was introduced to Stumbleupon. I was already aware of the name, but hadn’t investigated. I’ve joined and have spent several interesting but not very productive hours stumbling pages and pictures. When you create your Stumbleupon profile, you say which subjects you are interested in and when you click the Stumble! button on the browser toolbar, you get a page at random that matches your subjects. I have found many interesting websites through this and will add any that I find independently. If you like to find pseudo random pages that you would be interested in, I cannot recommend this enough.
One warning, its quite difficult to stop stumbling, you keep telling yourself ‘just one more’
