Even thought it's actually been available for a weeks, today is the "official" publication date for Groundswell. That means it's in stores all over the US and on iTunes and Audible as an audiobook.

We created this book to help people take advantage of the social computing trend. But is it actually useful? Only you can answer that question -- and we'd like to hear your answers.

We love bloggers reviewing the book, but you may not have a blog, or have time to write a few paragraphs. So why not make it easy. Twitter your review.

Start your review with "@Groundswell" and keep it to 140 characters. Why? Because it enforces some discipline on your thinking. And because it makes it easier for the rest of us to read all the reviews.

If you're not on Twitter, you can certainly write a 140 character review in the comments below.

Or you can leave it on our wall at Facebook.

Want to see what others are tweeting, use this Summize link or this Tweetscan.

(If you haven't read the book, what are you waiting for? Buy it here or here.)

Around May 15 we'll highlight the most interesting ones in a post on this blog, and we'll be retweeting them from @Groundswell on Twitter.

Looking forward to hearing your ideas!
