Well I thought I knew about a lot of sites, but this Periodic Table of the Internet has definitely shown me the way! I’ve found a lot of sites I didn’t know about, like Unclutterer and Found Magazine.
I bet there are a ton on there that people reading this haven’t tried, like Freecycle, Ubuntu.com, Homestar Runner and Venganza.com (home of the Flying Spaghetti Monster!). Give it a shot, even if you think the internet is stupid and a waste of time. There’s a few fun sites on the table but there are tons of really useful and helpful ones!
