Well, posts could be 5 and comments unlimited but rewards on comments for example could be only 50%.
Alternative accounts unfortunately is hard to tackle the problem :/
That is true, i'm also thinking of investing part of my salary in steem, since i trust the future of the platform...right now i'm thinking on how to do it, maybe coinbase account and then blocktrades, but i will wait to see if steem will drop the 3 dollar mark and then i think about doing it. ;)
It would require a separation of the pool to allow a separate amount for comments. Something I am not completely against.
