My guess is that hydrogen busses suffer the same challenges as hydrogen short-distance trucks. Due to an overall low energy efficiency (electrolysis -> compression -> decompression), it makes better sense for long-distance transport.
We tried in Denmark (Aarhus). Quite expensive, and too many issues. Electrical busses (with dedicated lanes) seems like the better solution, bus but this is also not cheap.
You raise a fair point. Hiding downvotes could help avoid bandwagon negativity, as users may be less inclined to pile on additional downvotes. However, I still believe transparency should take priority over these concerns.
Showing the full picture - both upvotes and downvotes separately - allows users to more accurately judge content quality and community sentiment. I think we should trust users to make reasoned judgments, rather than hide data from them. A slight potential increase in negativity seems a small price to pay for maintaining transparency and accountability on Lemmy.
Edit:
I do agree that displaying a relative percentage, as you mention, could serve as a compromise.
This missing feature is absolutely crucial for transparency.
Big tech industries are hiding downvotes, which obfuscates the true value of shared content in the eyes of the users.
I was excited to see Lemmy natively going against this trend, and saddened to see that it's not featured in sync (yet?).
