3 month ago, trial of 30 days with 1%, post link

Beneficiaries, from this version eSteem mobile has esteemapp account as a beneficiary for every comment/post made through it. As a trial run for next 30 days, 1% of the reward is shared with esteemapp and used for further development of the project. I hope Steemit will also introduce beneficiaries to bootstrap competition among different Steem apps.
