Website ideas?

So I have a passion for making websites but I'm really stuck. I want to make a website but I have no idea on what to make.
I don't want to make a forum again, perhaps something that people might be interested in. I dunno.
If you have any ideas then let me know on here, it can be multipurpose.

Multipurpose
It can consist of more than one thing.
Example: Forum and Chatroom.
I ain't making something like that though, it needs to be something interesting.

I'm bored and need something to keep me busy.
