The name "Stacker News" is vague. For a good 99% of people (including Bitcoin-aware people), "stacker" doesn't relate to Bitcoin.
I don't know how you got to this conclusion but I strongly disagree. I think the name is perfect. I also like how it's inspired by Hacker News.
SN uses Bitcoin as a technology to reward/incentivize activity, but it's never very clear (or explicit) that SN is about Bitcoin only
Maybe because it's not? You don't find any specific thematic content because there is no specific thematic content. We just post things we think is interesting to other people here.
Since bitcoin is what brought us here (common denominator), it's just natural that we discuss mostly bitcoin-related stuff here. However, nothing stops you to post something else. And in my opinion, there should not be anything. However, you sound like you are suggesting there should be.
You can already literally post anything here, nothing stops you. The question just is: Do you think it's worthwhile to pay for it?
Is the goal to make a monetized version of Hacker News? Then the topics could be much wider (as it is on HN, where you can find links to subjects ranging from IT to education, bio-hacking to philosophy, and pretty much anything in between).
I created @hn and it reposts top posts from HN and the posts get some attention.
I love Bitcoin and I've been advocating it for about 10 years
To be honest, I don't believe you. You have proof? For example, signing a message related to a transaction from 2013?
