People don't understand how VALUABLE the information you just gave them is! I'm s social media consultant and I'm always telling people that the ultimate goal is to get CONTACT information from your followers. E-mail is STILL your friend and very effective. Phone numbers are even more important. Yes, it's old fashioned but getting phone numbers and addresses can help immeasurably stay in contact with your hard-won followers and potential clients. Bravo for this piece.
