I hope that I will soon find some time to start my own witness server in order to pay part of my bills with the block production rewards.

You'd have my vote. I have wondered in the past why you are not running a witness node. Seems like a no-brainer as you're really dedicated to Steem and you're doing all this work on a great tool... I see no reason that you should not be at least top 50 witness by now.

I'm glad you've decided to start these support posts. My suggestion is to post more. I can understand the hesitation to do a daily post or something because of the expectation for "content," but if we can support off-chain videos, livestreams, audio, and images with our votes, we can certainly support development of such important tools.

Another option would be to go open-source and receive support through @utopian-io. Have you thought about that at all?
