yum yum yum - Delicious

Why have your bookmarks/favourites stuck at home on your computer when they can be available online for you to use and share. Delicious is my top web 2.0 tool, really couldn't and wouldn't be without it. 
Rather than huge long lists of websites you've saved, Delicious lets you tag the stuff you love, making it easy to organise and find later. You can even import stuff that you've already got. 
It's also a great way of finding great websites (well if someone has bothered to bookmark it, it might well be useful!)
There is even an iphone app for hardcore geeks.
Take a look at my bookmarks below - new stuff is added all the time!

prezi

Many of you have already seen PREZI.

I find it a really great presentation tool - it's non-linear nature means you can move around easily, go back to a previous point or skip ahead if you're running out of time.
It also encourages you to keep your text short - no more death by powerpoint!
take a look at the prezi showcase for some great ideas, you can also see a couple of simple ones I've done embedded on the new library website
