Well, I agree with the feeling, I don't have Facebook on my phone and very often the only available info is there. It's even a reason to avoid visiting that place.
FB Pages were so convenient, quick and free, but nowadays those are just horrible. I hope shops stop using them, changing to another service, or joining to the trend of microsites... Let's see!
What is bothering me currently are the restaurant menus and any info only accesible by QR codes, being a 40 MB PDF not optimized for mobile, a redirector full of ads, an unusable web page with tiny images, or even better, without prices for the food.
