What makes a Steem Witness, a Top Steem Witness?
Answering this question is - of course - subjective. For me, the following aspects apply:
A Top Steem Witness ... :
- runs an active & up-to-date node, as a bare minimum requirement;
- engages actively with the community;
- is skilled technically;
- understands the Steem Blockchain on multiple layers of interest;
- adds value to the Steem Blockchain & Ecosystem.

Hive account@holger80: arguably the most under-valued Steem Witness "Gem"
Hive account@holger80, at the time of writing this post, is ranked #89 on the WitnessRank at an approval rate of (now) 5,135 MV (1.29% of total); ref. https://steemd.com/witnesses.
Come on people, that is not a fair rank for him! Hive account@holger80 deserves a MUCH HIGHER Witness appreciation, so please meet & vote for Hive account@holger80, and here's why:
Hive account@holger80 is the core developer of Beem: a highly advanced Python library to interact with the Steem Blockchain. For those who don't know about it: Beem is the code on which many dApps are built on to use & interact with the blockchain. You could therefore say that if it wasn't for Hive account@holger80 and his tireless efforts to keep Beem fully uptodate, highly advanced, and completely (backward) compatible, then Steem would not be what it is today. And Hive account@holger80 does all his work for FREE. Also look at the Beem Documentation Hive account@holger80 wrote: can anybody show me an even more professional documentation on another project? Hats Off to Hive account@holger80!
Hive account@holger80 is also my colleague on UA 
Hive account@steem-ua: he's been a tremendous help on developing & running UA & the Hive account@steem-ua algorithmic curation program using UA data.
Hive account@holger80 also developed Steem Witness Tools, an Open Source repository including scripts, tools and documentation for other witnesses. He is helping other witnesses to make their technical tasks easier, from which everybody on the blockchain benefits. And again: he did that free-of-charge.
Hive account@holger80 has developed https://beempy.com/ During and right after the HF20 HardFork, nobody knew exactly what are the Resource Credits (RC) Costs for specific individual Blockchain Operations. I asked a few Top Witnesses myself, for example "how many daily comments will a 10 SP Plankton account be able to broadcast?". Nobody knew..... But Hive account@holger80 to the rescue! He wrote the code able to accurately compute current Resource Costs, providing info nobody knew before. You can simply visit https://beempy.com/ now, look up your own account for example, and see exactly what you can do right now!
Hive account@holger80 may not be "loud" enough to stand out from the crowd. He may not be the best "Self-Promotor". So let me vouch for Hive account@holger80 then:

Thanks for your time!
