This was a handy website I came across on some blog I don’t remember (probably lifehacker!). It allows you to create lists of websites for different causes. Like, the list above is one I use for my first year students. It’s growing, but not TOO fast. I don’t want to overload it with way too many links and websites that might not be that good.
You can tag the sites and create folders and categories as you like. Very good!
