Yeah I think a lot of people see it that way. I'm not a fan of FB, which is ironic given I'm supposed to be taking over the social media marketing for the school, and while I can see bands not using it like it could be I really don't care because I don't really want to use it.
I used to visit band webpages every few weeks for news and updates, but these days I couldn't even tell you when I last visited one of the leading band's websites, because I know what they are doing and roughly when albums are coming out. I don't generally visit label websites and I'm more likely to visit a store (amazon etc) to check a price than I am to look for a news update on a band site.
For whatever reasons there are I just don't use the internet the way I used to and I'm sure other people are the same.
