Huh? Well, Reddit is a platform, not a community. A sane usage pattern is to come for a sub, create an account and immediately unsubscribe from all the other subs. I find the communities I participate in not as bad as you describe. But a community defined as "everyone who cares about politics" is simply doomed. Now, to answer your original question: the value Reddit provides is having a single account for all my communities, instead of registering to umpteen PhpBB. This allows for a much more efficient antispam. Also more efficient ads, so they do have a business out of this.
