Ever use a crowd to learn something? I have. Here’s some of my favorite ones:

1. What Netbook would you recommend?

2. Examples of “now” marketing.

3. Teaching me about microformats.

4. Top apps to load on your new iPhone 3GS.

5. Favorite Twitter app for iPhone.

6. A bunch of people’s favorite web sites.

7. Tools people use to build 2010 websites.

8. Hundreds of people teach me about “leadership.”

9. What apps/services people think should be included in a list of 2010 web ones.

10. What to do if you see FriendFeed spam.

11. What to use instead of PowerPoint to give presentations.

12. What should CIOs consider about the 2010 web?

13. Interesting groups of Twitterers.

14. Should you use Disqus, Intense Debate, BackType on your blog’s commenting system?

15. What kind of mountain bike do you recommend for $1000-$1,500?

There are plenty of other examples too, but most of these have very good answers and are participated in by dozens if not hundreds of people each.

Have you found other examples of where crowds were used to answer questions and where the answers that came back are better than what you can find elsewhere?
