Keeping track of what you want to learn?

I spend time trying to learn specific items; then during my breaks I'll surf HN or Reddit and see a couple items I want to follow up. But a lot of times will forget until I come across it again.<p>I know of Evernote, just haven't used it much and not sure it will fit this instance.<p>Is there any situation where someone has grouped what they want to know by links/time spent look at subject?
