I'm really just waiting for the Netflix social network, if they'll ever have one anyway. The way I see social networks is this:
Google Plus: professional, newsworthy and, searchable social content.
Facebook: clean, simple and, a place for friends.
Twitter: a place to say something quick and to follow your favorite celebrities.
Instagram: a place to share pictures with family and friends.
Tumblr: A blog with a real time feed that supports gifs? (To be honest, I tried really hard to get into it but couldn't)
Path: still doesn't know what they're trying to do, a little to much information is taken and shared so maybe for your significant other?
Netflix having a social network for the purpose of movie fan lovers would be wonderful. I'd really like to see some kind of merger between IMDB so Netflix could still have a social experience with movies they don't "own" that could possibly even get movies to Netflix faster is something is "trending".
Just an opinion with a thought.
