While I don't have an opinion on Golos (never used them, they could be moving well in the future, who knows until the future gets here)

I praise good-karma for doing what is right for him as a focused developer.

Supporting both platforms, soon to be with totally different architecture, is bottleneck for advancement of eSteem project.

No, don't bottleneck yourself. eSteem continuing to be a solid app is very important for the steem blockchain.

I'm glad you decided to focus on that instead.
