Long-term storage of hyperlinks for future reference?

I frequently just email myself links to sites or articles I find helpful (usually some permalink to a specific comment buried deep in a thread that was the answer to some technical issue I had). There are probably close to a hundred of them now in my email. Do y'all have a more efficient / effective way to store these and some notes to self with them that won't keep eating up inbox space? Also looking for a solution that isn't OS specific, and accessible on any device via cloud-something. Solutions?
