I was just about to type something along those lines, but then I thought for a second and realized that a lot of these insane JavaScript projects coming out may never become the next <whatever is cool with the kids>, but the technical achievements made in each of these projects inspires the NEXT group of hackers that might be working on <next awesome thing>.

So I think there is a lot of value to these hack projects even if Facebook isn't going to roll it out in it's next update.

Engineering is like art... we all look at what each other is doing, get inspired and move the entire discipline forward.

What I love about that is you never know when you are going to inspire something, not with a project, but maybe just with a particularly nice snippet of code or data model that is SO intuitive, they feel compelled to work it into something.

Equally cool, you never know when YOU will get inspired. I know I've honestly read class definitions or parser implementations that were so intuitive and elegant that I have developed a compulsion to go code something that uses the same technique because it is so pretty.

I don't know why, but I think that is what makes this line of work so great. It's technical AND artistic... and it doesn't always make practical sense ;)
