Website Idea

I want to make a website. I have the knowledge, the gear, the time, the money to buy food. The only problem is that I have no idea what to make. I had some but they all turned into Wikipedia...

In my vision the website should:
- be usable anonymously (i.e. no accounts)
- have a very simple concept and layout
- be user-contributed
- not recreate anything that already exists
- solve a general problem online
- be legal to operate, at least in some countries (meh)
- fit into less than 50 TiB of storage and be usable with a 10 Gbit/s uplink

If anyone posts a good idea, I will implement it and post a link here in a few months.

Hey OP. I had a super simple idea for a website that lets you store equations on your account so you can easily retrieve them from any computer you're on.

It would have a section for equation name, assumptions, comments, etc.

The website would also have a general area where you can search for equations. It would be super simple to code. The challenging part would be building the database of equations while making sure you don't have a bunch of redundant shit. I was going to do it but I didn't want to buy the server hosting and you can't really do this on a shared one since you need to install latex and all that jazz.
