HAHAHAHA no. Reddit is not a good model for much of anything. To start with, they're solving a much simpler problem. A large percentage of their claimed 1.6B users per month are pure drive-bys - outsiders who followed one link one time and then left quickly. That's not the same as two billion users actively posting and interacting with content. Also, their data model is simpler. Even a hundred thousand subreddits are easy to model and manage compared to the "social graph" which is unique for each user. Even with that smaller scale and simpler model, they're not even trying to address some of the interesting problems such as privacy. You post something to a subreddit and it's visible or not - even to those casual visitors - according to the subreddit's settings. You don't get individual control of each post's visibility, which is essential for many people to control which sides of themselves they show to which groups of friends. Reddit is shouting in one of many town squares, and can be nothing else. Facebook can also be used that way, but for many it's more importantly a way to have more private interactions. Reddit doesn't even try to solve the interesting problems, so it could hardly be considered a model for solving them.
