wow! Less than a hundred accounts with more than 10K Hive are really very few. Especially if you take into account that several witnesses are included in that list.
Perhaps the most interesting thing would be to know how many of the Splinterlands players actually know about the existence of the Hive and how it works. Perhaps, the vast majority of these players have never interacted fluidly with Hive due to the complexity of the multiple viewers (peakd, ecency, hive.blog, etc...) and it is very likely that they are registering with another username on each platform.
For example, Splinterlands always points to Peakd for most of its proposals, but I dislike Peakd and prefer Hive.blog, so every time it sends me there, I have to do extra work to see the document on Hive.blog which is the viewer I prefer. Things like this are what fail to achieve true integration between Hive and Splinterlands.
One way to get an estimate of how many Splinterlands players are aware of Hive is by measuring the number of posts those players have made. I believe, based on educated guesses, that no more than 300 players have ever posted to Hive. If players do not publish, they cannot have Hive power, much less think about making investments in Hive.
And I, who review the posts on the Splinterlands tag every day, can assure with great certainty that the vast majority of those posts are only made for the reward and are always the same authors.

In fact, for entertainment I find it interesting to pull those numbers from the blockchain and determine what actual percentage of Splinterlands players have interacted in some way on Hive.

But, in any case, if there is a large base of players who know Hive, and who can contribute to its development, Splinterlands should somehow encourage them to actively participate with small steps, such as each player doing their duty and vote for the 30 witnesses of their choice. ...
