I personally think one of the benefits of reddit is the fact that you have access to essentially unlimited forums with the same identity. Oftentimes I am working/pondering something and I'd like to ask someone involved in that specific community a question. Without a "reddit-style" identity system (I know there are "security concerns", etc) it looks like I need another username and password for this niche phpbb forum. I think the reddit community lowers the barrier of online discussion to a degree that if I wanted to I'm one post away from hopping to another niche community to ask a question.
Yep, I like the idea of reddit-style online identity. It's almost effortless to create dozens of them, you can use them in any subreddit, and you don't even need an e-mail address to sign up.
Hopefully, if & when everyone starts using Persona, it will be nearly as simple to start using a random website as it is to join a random subreddit, and we will finally be able to stop being members of excessively large "communities" like reddit and fb.
