The other problem is that you might not be interested in what some people find cool.

StumbleUpon deals with both of those issues with one little, easy-to-use toolbar.

It's a free service that puts you a click away from online content -- videos, photos, wikis and sites -- that you want to see.

Intrigued? Check out my new Cat With Mouse column and find out how it all works.

I'd love for you to give StumbleUpon a whirl. Tell me what you think and what you find online!

And if you have any story ideas for me -- things you'd like to see tested or explained -- drop me an e-mail. I can't wait to hear from you!
