That's a great article, thanks for posting it, Emily!

Here are my "can't live without" 2.0-tools:

- Bloglines - my RSS aggregator of choice and definitely the one I use *the most*!
- meebo - my IM client of choice, following on the heels of Bloglines for the second-most used!
- del.icio.us - the #1 social bookmarking tool in my world (unrelated sidenote: I signed up for del.icio.us so early that I got my first name as my username! That almost never happens!). Although Arrington mentions that BlueDot is his #1, so I'll have to give that a go soon...
- flickr - not only is flickr where I store and organize my own photographs, but it always provides the perfect diversion when I need one. Just do a tag search for something that's on your mind, or something you're interested in and I *defy* you not to get sucked into hours of browsing!
- pandora - if you spend as much time in front of a screen as I do, you probably already know how much better pandora makes that time! I use last.fm a fair bit too and I really don't think I could choose between them!
- wordpress - it's been my blogging platform of choice for close to 3-years. I'd be lost without it!

OK, how about everyone else? If you had to choose ONE 2.0 tool you couldn't live without, what would it be?

i know that this is not a popular sentitment with librarians, but i love google's personalized, multiple-tabbed homepage, which synchs nicely with gmail, writely, google reader (with multiple/tagged views by category w/out going into the reader!), and even personalized search feeds. i feel like i've discovered the collaborative writer's dream! (i'm sure i'm missing out on something by going for all this integration, but it's nice to have it all in one place.) what I don't use google for? images & social bookmarking. so, my runners up have to be flickr & de.licio.us.

Some great replies so far. I especially agree with Chrystie that integration is good. Here are a few of my favorites:

#1 Del.icio.us -- The best thing about Web 2.0 as far as I'm concerned. It's been years since I actually used my IE or Firefox bookmarks on a regular basis as a way to organize information. But I use delicious several times a day, and I generally have no problem finding sites that I've tagged, especially with <a href="https://addons.mozilla.org/firefox/3615/">the latest Firefox extension</a>. This extension replaces your normal bookmarks menu with several different views of your tags and bundles. It also makes searching your bookmarks really fast and easy.

Furthermore, delicious is one of the best discovery tools out there. I start most of my technology research here.

#2 Google Reader -- I abandoned Bloglines a few months ago and haven't looked back. Bloglines frequently failed to update my feeds for some reason. And GR just looks better.

#3 Finetune -- Finetune lets me create a station out of songs that I pick rather than songs it thinks I might like. I still listen to Pandora a lot, but lately I've been more attached to FineTune. There are a few catches (no more than 3 songs from any one artist, a minimum of 45 songs), but these restrictions seem reasonable to me.

#4 EMusic -- EMusic is an alternative to ITunes that charges roughly $.30 a song, as opposed to $.99 a song on ITunes. And there's no DRM on the songs I get at EMusic, so I can play the songs anywhere, on any device. I just signed up, so maybe there's a flaw somewhere, but everyone who mentions this service raves about it.

Also didn't appreciate how many Web 2.0 companies that I use constantly, especially Gmail, Pandora and Skype. Since I relocated a long way from my family, these really help keep me connected.
