Sherlock makes pretty graphs of your internet history. Check out a few of these graphs below.
On this graph, each dot represents visiting a website once. Only my 16 most visited websites from the past 3 months of browsing while on my laptop and using Chrome are shown. Since I generally use my phone in the morning, my desktop at night, and Firefox for dev, this data is somewhat incomplete.
I generally don't use the internet from 11:00 to 8:00. This is partially because of the use of other devices and browsers, but matches up with my sleep schedule fairly well.
This graph really highlights how my internet usage is dominated by just a few sites. Google, Imgur (via Reddit), Github, Facebook, GMail, Youtube, Reddit, Stackoverflow, Google Code, Wikipedia and Google Drive are where I spend the vast majority of my time.
resme.me is for the Reddit Enchancment Suite; it is opened on every update.
d20pfsrd.com is a D&D site which I use very occassionally.
I've read a few articles on businessinsider.com.
Really, I only use about 10 sites on the internet regularly. This seems pretty damn small considering the millions (more?) of sites across the world.
This graph is just like the one above, but with a different time scale.
This really is the wrong graph for this data. A daily or hourly bar chart would be much better.
