Have been having a look at Furl and del.icio.us. Both seem great little tools. And there's a ton of commentary on their relative "under the hood" merits. The functionality seems to be slightly better in del.icio.us - but I'm going to choose furl.

The only reason? Because it seemed easier to get going with it. I'm not codeophobic but when someone else has done the hard work for you ...

Watch that sidebar to see quite how much rubbish I'm talking ;-)

[Update#1: Yup. Rubbish. Now I'm using del.icio.us here
