Website ideas.

I'm thinking of forming a website, but I honestly have no clue as to what I should make for one.

I basically want to make a website totally from scratch, or with a small base and completely blow it out of proportion as I more along with my web programming knowledge, making this one site better and better and better, along with other small projects.
IDEAS, GOGOGO!

Something with some originality in it, not something that's been whored 45 billion times.
