Still useless at this time; many functions useless if you don’t link a Facebook account!
I didn’t think Facebook was still relevant in the US! especially in relation to artistic gatherings such as BottleRock Napa! I am surprised that out of all social media networks known worldwide, Bottlerock chose to partner with Facebook for this app. :( Please be advised that this Bottlerock app forces you to link it to a Facebook account. Thus, if you don’t want to link a Facebook account to the Bottlerock app, many functions on the app will be USELESS. Also, at this time, there is little info available on the app. Hope the app improves in time for the festival.
