Hello again @crypticat, you've hit on a very interesting issue here, let me say that I very much agree with the way we generally see an attempt to reflect superfluous engagement within Hive, this however, is what I would like to try and change, but of course it's a job that will take a lot of time.
I am glad you took the time to tell me how you see the reflection of this, when others comment on your blog, it is helpful for us to understand your point of view as a frequent user. It would be great if when someone stops by a post, they do it out of interest and enthusiasm, as you describe you actually do.
As for your suggestion about the travel category filter, it is an interesting idea, I take note of it, because we plan in the future to expand features of the map to make it more useful to all travelers who access it, both inside and outside Hive. We can't promise anything concrete yet, but we could consider a different way of filtering types of experiences.
