You know, when I've been watching videos on youtube, I could jump between similar tagged videos by the "Related Videos" feature. It's fun, and you can discover a lot with it. I think it will be great to have this feature on Scratch website (below the description box, and above "other author's projects" box).

Tags are already kind of like that; they let a user choose what they want to describe there project as, and then on a project when you click tags, you can find other projects with the same tags! The problem with a related projects function is that, the website would have to be "smart" enough to find similarities and differences between projects. If a user got to choose them, it would be just like tags!
