If I'd build a website business, it would be like these..

instagra.am dropbox.com animoto.com posterous.com slide.com ..

All of these have a beauty coming from the simplicity/clearness of the idea behind them.

As soon as I hear about one of these I'm thrilled by that aspect - and it's part of what makes you feel or say - I'd use this yeah.

Do you know of an online listing that would group such websites - I feel like there's a lesson to learn from these - there is a pattern in all that escapes the eye?
