Yes you have normal accounts for those stuff. So we have a solution for commenting and voting and all the rest of the stuff. And it's only 3sp... so it's almost free but it's a big barrier because who has 3sp? Well maybe a light account can get 3sp and then pay for an account or have an account gifted to them i suppose.

For example what steempeak would like is an account that a user could use anywhere that basically has a wallet and the ability to sign in to something and work to transition it to a normal account.

But yes you are correct this is primarily an account for logging in and tokens in my opinion... not as much for the social media aspect. Lots of other uses of steem beyond the blogging and staking and rewards systems.
