That's what I refer to shoehorning. It's very common with tribes for people trying to get as many tags that will payout rewards as possible. The Bitcoin one is a good example, yes Bitcoin is a technology, but talking about price isn't STEM.
I'm hoping this change reduces the damage done by this, but the community does a good job cleaning it up. I don't have to step in too often.
I actually wrote about this, mostly from the "battle for traffic angle" last year (it gets interesting in the comments).
This should long term also have an influence on token value. Less accumulating for the sake of yet another token collected and more targeted content, plus the SEO bonus will reduce token dilution the "get paid for using tags" method causes.
STEM already has a very low inflation (perhaps even too low, especially at the current price). STEM isn't as popular as crypto on Hive.
I look forward to the first reports about the outcome. They should be interesting. If effective immediately, the first seven days should be a great benchmark and then to see how it evolves every month.
I think low inflation is good. Better to have it early rather than grow some big whales because of high initial inflation. I also still believe in "complexity" as a factor. Changes like this, combined with low inflation, can mid- to longterm only be beneficial on token value. Especially because STEM is a very passionate niche and one with monetization potential beyond "engagement" and pageviews, where people don't always understand the scale both those require to make an actual dent in token value.
BTW one minor thought: I would not (yet) implement it on comments. Not unless there's actual comment farming, which I doubt. Not under your rule lol.
The notifications ecosystem doesn't really offer any great user experience for comments.
