So I've set up the #retail10 hashtag and I would love it if while you're out and about, you could talk about what you're seeing. Just Tweet or if you write larger posts, put links to them on Twitter as well. I'll be compiling them over the next couple of weeks and sharing them both here and through paper.li.
I've already started, so you can see some ideas of what I'm doing. Quick observations, customer counts, great deals, what people are buying. You're probably tweeting about your shopping experience anyway, why not make it part of a larger, retail picture.
Thanks for your help!
