I'm one of those people that has a service/app for almost everything I need or do: managing what I eat, sleeping schedule, finding new music, learning new skills (and practicing them), etc. My friend Mat is similar, so we decided to combine a list of sites we've used and found useful in the past to make randomusefulwebsites.com If anyone has any ideas, please submit them using the link on the site and if they're decent, I'll get them added!
