I use the Evernote plugin for saving random snippets of interesting text I might want one day; and for pages I'll want to visit in the next 6 months, I use 'Read It Later' http://readitlaterlist.com/

What's so nice about read it later is that it's quicker than regular bookmarks. I hit alt-w to add current page to the list, alt-w to remove it when I'm done, and that's it.

The regular bookmarks are heavyweight enough that I just wouldn't do that. (And this allows a nice division between regular bookmarks, links I'll be using for years, and RIL bookmarks, which I could get rid of anytime as soon as I finish with them. I could do that with folders, and that's how RIL works behind the scenes, but that's still more heavyweight.)

There are other features, like auto-saving the pages to disk for offline access, or a personal RSS feed, and integration with various Web 2.0 thingies - but that the core functionality is so quick and easy is the greatest part about it.

I tried delicious for a while but it never really clicked for me. I now use Xmarks with Firefox and love it. It keeps my bookmarks the same on my several personal and work computers with different views for each, not to mention it syncs usernames and passwords.

I use InstaPaper for stuff that I want to "read later" as is its intended purpose, or stuff that think I might want to return to occasionally. I like that I can get to it from anywhere, doesn't matter if I'm using my local machine.

For pages I use all the time... I have a local HTML file as my home page. It's just a simple set of links organized into a few broad categories. Faster than navigating the browser's bookmarks, for me, though slightly more work to update.

I got through hundreds of site a day and never bookmark them. For me the internet is more an experience and I don't' like to read things twice. I can usually find what I want very quickly using google. So my suggestion is to just use google.

The problem is when I _want_ to remember things for certain ocasions, like, showing something to a friend, or just revisit if there is a need to. Google sometimes is inefficient for that.

I use standard issue Firefox bookmarking, including a large group of bookmarks imported from the last time I was using IE. I refer to those bookmarks often during online discussion--I just did this afternoon.

Browser autocompletion, with Google for the tricky ones. I visit the same 6 sites all the time anyway.

I figure that if I can't remember a useful keyword off the page, it must not've been a site worth remembering.

delicious, pretty much since the day it started. Probably would not be using it that heavily without the Firefox plugin. Ctrl-D is one of my more used actions.

Browser bookmarking with TagSifter in Firefox.

I still fondly remember Kaylon's PowerMarks. Tagged bookmarking, with auto-generation of a default set of tags and with fast search based on parsing input to a textbox. It may still be around, but I believe development stopped years ago.

Searching on "TagSifter" turned up

which gives me it and two other Firefox extensions to look at further when it's not so late in the evening.

Maybe the combination will get me close to what PowerMarks offered.

A combination of Instapaper for PDFs and the like, with Delicious for everything else.

zotero for saving pages that I'll want to see again or want to be able to search locally
