Looking over games, blogs, news sites, etc. one thing strikes me about the future of ALL businesses.
All businesses are going to have to be customer-engaged to succeed. They'll need posts, comments, Tweets, emails, FAQS, forums, and more because THAT is the new normal.
Part of this is the influence of social media, of course (as I noted, social media is normal anyway), but part of this is the accessibility the internet provides. People expect to be able to communicate, get answers, get information, etc.
