How to systematically capture notes, links and other bits for future reading or reference

As a new computer wings its way towards my office, I'm doing some digital spring cleaning.

One of the things I find hard is keeping on top of blog posts, news stories that I really need to read, but don't always do so right away because of pressing client work, etc. And even if I do read it, how do I quickly find it again?

Should I set aside half an hour each morning? Should I have a hard and fast rule that once I start reading a blog post I MUST finish it and decide there and then on an action: blog about it, bookmark it, file it for future reference or move on?

It gets even harder when I'm researching on behalf of a client because then I do need to record what I've found in order to report back.

So far I've tried using various tools including Google Notebook and even just bookmarking on del.icio.us.

But I recently came across this brilliant post by Steve Rubel in which he sets out 3 methods of capturing notes or bookmarks, including using a FriendFeed room as an archive. I haven't tried them yet but I will do, as they seem like great tips.
