A place to store all the interesting articles found online

Hi, I'm looking for a place where to store all the interesting articles I find online and maybe see what other users find online. Up to now I used Twitter (https://twitter.com/nerusskyhigh) and LinkedIn but judging from other's posts I think this may not be the intended usage. I don't want to use bookmarks because they'd cluster my already long list of saved sites and, a plain text file risks being lost or becoming too large to maintain. Any advice or useful site to share?
