Delicious is just that. WOW lots of great sites. Just exploring math topics and I was overwhelmed. I found all new sites. I love the British. They have great ideas for children.
I found that you can find the best sites by looking at how many people have tagged that site. And usually that site is a winner.
Oh yes, I will use this. I have all the little buttons on my Internet Explorer and they certainly make it easier to tag sites. I look forward to finding more site, but right now I have to keep moving through the THINGS!!!!
