Have you looked at Google Bookmark and Google Notebook? That's what I use. Note that bookmarks also appear in the notebook, but that interaction isn't what you would expect (as the bookmarks have to stay in the "unfiled" notebook or they become inaccessable through Google Bookmark). Both also have a firefox plugin - the bookmark allows you to add a menu bar item to access your bookmarks and notebook lets you "clip" pages.

I use foxmarks for my bookmarks - it's just for me, not the world, accessable anywhere, with or without firefox.
however as for other notes, i haven't got a likeable solution apart from using unpublished posts on a blog
maybe someone shoud write one... I wonder where we could find a programmer ;)

I use Evernote. The best part is the mobile integration.

I use Todoist for my information storage. Although primarily a "to-do" list site (which I also use it for), it powerful enough for me to be able to store anything else there and catogorize it accordinly using projects and the various plugins.

I use Microsoft OneNote. Whilst it's great on a Tablet PC (why won't someone make a good tablet??), it's still just as useful on a normal PC / PDA!

I currently use Del.icio.us as I like to have my bookmarks available at home, at work and where ever else I happen to be. There have been moments during pair programming where I've browsed my bookmarks from a colleagues PC to find an article I'd tagged which discussed a problem we were looking it. There is also a browser addon for Del.icio.us which allows you to search your bookmarks from within the browser and I find the ability to apply multiple tags to a single entry very useful.

I have only just started using Google Notebook, and I didn't know there was a Google bookmarks, but I shall be looking into that.

This is really an interesting problem. There is no single solution to solve it all :) Atleast as far as i know. Hope to get some nice stuff from here..

Google bookmarks is quite good. But i feel

the good

  • It works fine only for anything with URLs :)

the bad

  • The more labels you have, the more difficult it will be to manage
  • Can have only one level of hierarchy.

I used Idea Library on my Windows Mobile phone for sometime. It does some interesting things like you can add Voice based idea ;) and sketch based idea, etc.. You might want to check.

For bookmarks del.icio.us combined with the del.icio.us toolbar is invaluable. You can tag the bookmarks and use filters to only show the ones relevant to a certain project. You can also append notes to the bookmarks if you need more context than the tags can provide.

At the moment I'm testing out Goodreads for sorting out my book problem. It has, as far as I know, every book from Amazon and you can add your own. You can assign states to each book (to read, currently reading etc). It seems like a good solution but haven't tried it enough to say it covers your needs.

FriendFeed or SecondBrain could solve some of the "there is no site to rule them all" problem. They are technically "social bookmarking sites" but you don't have to use them that way.

All my bookmarks are on del.icio.us. I use it to also keep track of books, articles, movies and music that I wish to read/watch/listen in the future. All stuff I intend to do is tagged with TODO and depending on the media tagged with additional READ, WATCH and LISTEN tags.

So, it becomes painless to bring up stuff I want to read, for example:

<http://del.icio.us/myname/TODO+READ&gt;

Stuff to watch:

<http://del.icio.us/myname/TODO+WATCH&gt;

And after I'm done with them, I just remove the TODO tag.

Give a look also to Zotero, a good ffox plugin.

Foxmarks, and a Sticky Note app for iGoogle that just lets me put whatever text information that I want to store in one place.

I second Google Notebook, its a great way to organize lots of data and leave comments/notes to yourself. Also easy to share certain notebooks with friends or public.
