Enter Diigo. I’m surprised this excellent social bookmarking service doesn’t have a higher profile online. It’s fast, easy, and it saves a cache of every page by default. I really don’t see how del.icio.us can compete, considering that Diigo looks much nicer and still manages to respond more crisply. (Yes, there are other social bookmarking sites out there, and were I a true productivity blogger and not a dilettante, I’d give you a point-by-point feature comparison with a nifty chart. In this case, I’m going to fall back on “trust me.” Diigo’s the best I’ve tried, and I’ve tried a bunch.)

Use Diigo for static pages with useful content. Here are some suggested uses from my own Diigo love affair: Research. Why bother copying and pasting articles you’ll be using in your next paper or presentation when you can add them to a searchable database in one click? Publicity. If you have a blog, podcast, or other promotable work, you’ll want to clip all the reviews, blog mentions, etc. Diigo’s perfect for quickly and easily capturing those mentions for posterity and, since it’s shareable, you can show off your best clips in a snap. Want List. It’s not really a resolution, but I do plan to cut down on my expenditures in 2008, and one way that’s always worked well for me in the past is creating a “want list.” When I see a nifty notebook or gadget or safety razor I want to buy, I add it to the want list with the date. 30 days later, if it still sounds awesome, I’ll buy it. But often my enthusiasm for that nifty cable wrap I saw on Cool Tools has waned and I’ve saved twenty bucks. Lifehacks. Obviously. If you’re like me, you’re constantly gathering tips and advice on productivity and technology from around the Web. Save them here and go over them periodically to see which ones actually worked in practice and which were quickly forgotten. Recipes. Several recipe sites let you aggregate your favorites, but if you get your recipes from multiple sites, you can use Diigo to keep them all in the same place. Blogging. One of the big advantages of a social bookmarking service is the social part. Diigo makes it easy to share your links, post them to your blog, or even do an automatic daily post of links to your site.

Sourcing Track Digging Through Diigo Tim O'Connor ( Capgemini NA)

The most helpful part of Classroom 2.0 Live in San Francisco this past weekend was the lightning rounds and the product demos.  The ones who did have an hour, including myself, probably would have been better off staying within fifteen minutes.  Here are some products in the order of my personal preference: 1.      Diigo (www.diigo.com) is perhaps the most useful site I’ve seen lately, of course elegant in its simplicity.  It promotes a better version of social bookmarking with features that enable clipping, quoting, and annotating among much else.
