In no particular order:

1. One of the most attractive things about the Internet for me is the fact that I can read about 12 different subjects at once without cracking several books open. Add an element of randomness (using user-generated content), and my dreams have finally come true: Stumbleupon (Warning: Crucial Productivity Killer)

2. The Internet really is del.icio.us

3. Not only can you stumble on new stuff, but you can also talk about it in real time with others: Me.dium (Serious Productivity Killer. Consider yourself warned)

4. Everything should have a soundtrack: Musicovery

5. Discover and share: Yoono (very simple on the surface, but dig a little deeper to uncover more of its features. It’ll be worth the time)

6. If it’s really that precious, why don’t you share it? Email This!

7. Get smarter. Read reddit (not Digg. Another Serious Productivity Killer)

8. Write it all down with Google Notebook
