I figured that coding our own frontend would be difficult, time consuming and expensive

Agreed, however I was thinking long term plan, in case steem reaches sustainable price lvl.
I assume it'll happen sooner or later and having long term idea might be a way to go.

Most of steem groups fails to deliver since majority was literally playing with tools steem-engine provides,showing how cheap it actually is to build on top of steem and how easy one can utilize POB concept.

The fact is That steem lacks mobile app which won't have aggressive add spaces and that will provide nothing more than a pleasent UE.

Yeah, I'll contact you via discord as soon as I fix my laptop and catch some free time :)
