I used to use bookmarks, but then i became aware of how bad i am with actually re visiting the things i save. I had virtual piles upon piles of bookmarks that i would save and then promptly forget about. Now, i use the latest version of Opera which doesn't have bookmarks (kind of). If i see something potentially interesting i either take the time right then to look at it, or i don't look at it at all and hope i remember later but if not, oh well. For things that i know are important that i just can't get into at that moment (like, an album that i really think i'll like) I'll text it to myself and then refuse to clear the notification until i've re visited whatever it was. I feel weird if text notifications start piling up so that's always a good motivator for me.
