Seems like room for a text->Messenger gateway, or other ways of integrating SMS into a business's existing customer feedback channels. (Which probably exists in various forms of hacked-together-API-mashups already, since it's hard on a customer service team to manage a bunch of different inboxen.)

TalkBin (YC W11) was a platform for allowing customers to SMS local businesses, but getting brick and mortar businesses to adopt a new communication channel isn't easy.
