I use RSS feeds for my regular sites & save interesting things there. For other stuff, I set up folders under the main menu by category: cooking, finance, projects, bass, shopping, etc. There's also a catch-all "Unfiled." There are MeFi/AskMe folders with category subfolders & bookmarks left over from before I switched to RSS feeds.

Everything I bookmark goes into the main menu, and I try to drag them into the right folder right away unless it's something I'm going to access often or keep up as a reminder (ups tracking, threads I'm watching, Minecraft wiki, etc.) I go through every so often & try to thin it all out.

My Google Reader saved items, though? Now that's a half-tagged mess.

Here's a random "Unfiled" link: what if you only have £200? « English Cut

I manually copy my "favourites bar" favourites to any machine I am going to use much (e.g. my work laptop, or computer at home) but use del.icio.us for most stuff.

I also use a few tags in del.icio.us and sometimes will save a shortcut to that tag, so that, for example, I can just look at the guitar tabs I've saved.

I found del.icio.us got SUPER useful once I was able to use that little "post to del.icio.us" favourites toolbar button dealy. So, while on a page, I can just click on that button, and it prompts me to tag/save to my del.icio.us page, then returns me to the page in question. I can then read some if I have time, or close it and read it later.

A while back I used Xmarks (which is going out of business at the end of the year, DAMMIT) to consolidate my bookmarks among three separate computers, a desktop, a laptop and a teeny netbook... PLUS a second Xmarks account on one machine that I had forgotten existed... afraid of losing anything, I told it to "combine" and ended up with a MASSIVE pile of duplicates and triplicates. Then I put away the laptop for a couple months (considering it my 'backup' machine) while I worked on sorting, trimming and organizing it all. Before I was more than two-thirds done, I powered up the laptop and started Firefox, and it re-combined the unsorted mess with the sorted bookmarks on the other two. AAARRRGGGHHH.

I'm far from re-sorting, re-trimming and re-organizing, and once I got a few vital and favorite categories in folders the way I wanted them (Financial, Shopping, MetaSites, Local News & Weather, Webcomics, The Domains I Own [Whether Or Not I'm Doing Anything With Them] and Everything I Wrote For Other Sites That's Still Online) I have chosen to ignore the 40+ other folders below them (including topics I was going to write about or post to MeFi but never did and a bunch of WebDesign/WordPress/CSS/PHP/Fonts/Graphics/SiteTools but no SEO resources for my dormant websites)

I can't blame Xmarks for my bookmarking troubles and am really gonna miss them. It was a totally useful service that was sadly totally impossible to make any money from. There are browser-specific bookmark sync add-ons but Xmarks made it so much easier to bounce between Firefox, Chrome and sometimes even IE8 that the browser-specifics won't do.

I do have a My.Yahoo page I originally set up over 10 years ago that I still go to in order to check on news, the RSS feeds of favorite sites and what's on TV. I tried iGoogle's 'home page' but it actually was more difficult to use and update. But I've never bother with a full-fledged RSS reader. I may need to get more RSSophisticated...

I am a folder queen, in Outlook, in my email account, and re all my bookmarks. I periodically review and re-sort my bookmarks, and I use Xmarks current version every day to synchronize all my stuff, folders included, on my 4 different principal computers.

I love organization, what can I say.

Like bearwife I use lots of folders both in bookmarks and in email. My main bookmark folder is "Daily" which has, in order, xkcd, my local Wunderground (thanks to desjardins!), MetaChat, MetaTalk, and AskMe Anon. Others I have are Weekly (for sites like PostSecret, One Sentence, etc.), WoW, Shopping, Blogs and so on. I'll make folders for something I'm interested in that will probably get deleted at some point (Lighthouses, Canes, Rings, Costumes, etc.). If I don't keep them organized it'll quickly become a mess.

I like the daily and weekly folder ideas. Maybe I'll try that...

What is this 'manage' you speak of, earth creature?

The short answer is that my bookmarks are in no way organized. What generally happens is I bookmark a ton of stuff, then can't find the bookmark, end up searching google for the thing, then after a couple of years my computer dies and I move onto the new machine.
