if there was a website you'd visit often, what would it be.

-------
you're - you are. "you're stupid for never using 'your/you're' correctly"
your - a posessive pronoun. "you don't know your grammar"

The only reason I'm saying this is because anybody that's going to use your website will only use it if your site is professionally designed/hosted (i.e. it is fast, it works, and it looks good). This takes a lot of time and effort, so wait until you have a good idea before you make it. I find websites that post blog-like articles on certain things particularly helpful. For example, you could post resources to web design stuff, you could make tutorials, etc.

But no matter what you do, remember that you will have to make your own content. You will have to spend time... lots of time...

I once heard the voice of God.
It said "Vrrrrmmmmm." Unless it was just a lawn mower.
