I use a particular browser called Galeon which has as it's homepage all my favorites, by category. One such category is called 'networking' and in it are all the sites, such as this on, that I visit. I particularly like that way of seeing my sites, as it were, because it reminds me of which ones I've not visited recently.
So, whenever I've got 10 mins to spare (yeah, right!) I boot up my browser and hit one or two that I've not visited recently.
but it doesn't dominate my life.
