I was recently looking at the Shakespeare's Globe website. On the page announcing their 2013 season they asked their readers to:
"Join the conversation
Tell us what you think about the 2013 season. Tweet us your thoughts to @The_Globe and include the hashtag #Globe2013. Or add your comments on our Facebook page."
I liked this because they were asking for feedback, and making it really easy to provide (as they gave the hashtag, twitter handle and link to Facebook page).
I also liked that they were ready for people to comment publicly both good and bad (although I have to admit the 2013 program sounds amazing).
Does your organisation seek feedback this publicly? And is it this easy?
