Web surfing is almost non-existant now for me. I only use the internet for extremely utilitarian purposes. I miss the old days when I would make the rounds, follow specific places hang out on certain sites. Now its used for checking grades and writing email.
You can see what your most frequented sites are by going in Firefox to History/Show all history/More than 6 months. Then in the column of "Number of Visits" click the top to sort the visits.
The only interesting sites I see in my top 40 are ones that I forced myself to watch by making them my home page at various times.
