At least for me, there are two related issues: spending time in preparation for something I tell myself I should do but actually don't and the stuff I am saving in preparation for things I don't actually do overwhelming the stuff that I would actually use if I could find it easily. You can still bookmark and save emails just do so in a way that takes very little time and doesn't get in the way of what you actually use. With email is when it gets to be too much I go through and deal with everything I must reply to right now and save all the rest in a new folder that I can refer to if necessary (this occasionally happens). I started doing this by telling myself that I would look through them if I got the chance, but that never happens. With bookmarking and such the trick is to avoid letting the things you are most likely never actually going to look at get in the way of accessing the things you have read and want to be able to refer to quickly or are likely to be of particular use to refer to in the not too distant future (e.g. something related to a particular project you are working on). If you think organizing in a particular way might be helpful, try it but if you don't actually use it go to the lowest effort option (e.g. add an unsorted bookmark). Sometimes unsorted bookmarks can still be useful to find an article you remember looking at, although I often find it isn't possible in a reasonable amount of time so I've found the trick if I remember seeing an article I now want to read is to try a few quick searches of bookmarks but stop fairly quickly if I don't find it. I also find it helpful to completely stop reading HN (and other stuff that isn't immediately useful) for a month or two now and then to get a better feel for how much time it takes and what I get out of it.
