It's actually not what most likely expect. Even a 20% POB beneficiary is less than the 10% by posting on proofofbrain.io as that takes 10% of ALL tokens, not just POB, where as not posting on the site only takes 20% of the POB tokens only.

So in the end, if you use the front end you are giving up 10% of all tokens earned, including Hive. In most cases this is far more.
