The next great idea...

...is so impossible to think of.

I've been thinking what I could do as a web-app project, that for now is just so I can flex my e-muscles and get acclimated programming in JavaScript/AJAX yadda yadda.

I had an idea last year to make that web-based photo editor, I mentioned it in an earlier post, and yeah, that was the only sound idea I had. Right now, I need suggestions so I can get on track.

I have a couple of ideas I'm working on right now, mostly silly because it's hard. It's hard to think of the future! :(

Idea 1: A personal recipe cookbook type blog.
I say "personal" because I thought of this concept when I cook. I like to print off a recipe, and then maybe take notes. These notes would consist of what I thought of the recipe, results, modifications, future alterations, and anything I guess you would write reminding yourself of what you would do differently.

You could actually do this on a blog, but I thought if you could organize it in a more efficient database, you could make notes after you cooked, and so you could reference it in the future. This is just an alternative to a possibly endless and messy paper trail since you could do all this on paper.

But... what if... You could also get comments? This web-service could be more of a community-based tool IF you can have friendly group discussion. Eg. People could post their comments on things you've tried, and what they've tried.

This could blow out of proportion though with people arguing that you've stolen their recipes, but that's not really the scope of this. It's more of a personal cooking blog, but scalable so that you can share what you've tried to cook with your friends.

Actually... this works exactly like a blog concept. But unlike most food websites, I actually want to be able to store recipe data, and notes. A digital cookbook. A digital recipe archive.

I'm not sure, I still think it's a silly idea, but I feel that it has some merit.
Would love opinions on this.

I wrote Idea 1 up there as if I had another idea, I did... but I've forgotten again.
What have you ever thought that "it would be nice if there was a website that I could ....". I need ideas! I need the future!
