A quick note on importing content into facebook.
Should find a link to an 'import app' (my name) here:
You might find you already have that app loaded. If so...
Go to your wall tab
Where you see 'Update status' etc, you'll find an arrow. Click the arrow and 'import' appears as an option.
Click the sites you want to import from includes StumbleUpon, Digg, flickr, YouTube and more.
Modyo also looks interesting.
