The first site to be mentioned here: Smashingmagazine.com.

This website offers a lot of inspiration and knowledge about the internet itself. The website itself is well-known mostly from several huge round-ups. Think of graphic collections, blog templates, fonts, beautiful designs, etc. If you need some inspiration for a new project, Smashingmagazine is the site to visit.

The design is simple and easy to read, with a lot of categories to choose from. The only downside is the amount of banners on the right side, taking up a lot of space.
