Yes, quite right about revising habits from time to time. For me, I tend to leave tabs open when I search for something that I'd like to reference later, but have no need to keep as a bookmark. Once read, if it's valuable for later, I'll just move the website to the appropriate folder on my desktop. But, lots of things interest me and I never know what will grab my attention so this approach generally works. Since I keep open tabs to under 30, I don't think it hurts me much. But, it's always great to have a look. Thanks for you insights and help.
