I wish we lived in a world where people actually did what they signed up for. Buy unfortunately we have machines who follow that rule. I came on Twitter very late and it was basically to shame and acknowledged good publicity.
It's very true. I recently had an issue with Expedia and was getting no where with phone or email support. I simply tweeted their public account with 140 chars of details and boom, they had "coincidentally" updated their TOS which meant my issue was now resolvable.
