It’s true of all combat sports, and, to some degree, any other sport in which you go face to face with your opponent.

And although it might be true that at the very very top levels people both learn to be more ambidextrous (so that there’s less of a mismatch between sides whether right or left handed) and are more experienced/skilled at dealing with left handed opponents, the early years of learning the sport will weed out fewer left handed people so that the top levels have more left handed people.

Depends on the topic. From what I can tell, Lemmy skews young and technical and towards certain personalities and interests, so there are going to be topics that go to those strengths, but also topics where the discussions get mired down in either discussing the basics or get stuck in a pretty unsophisticated understanding of the topic.

It’s obvious with the hyper local discussions (where should I eat in this city when I visit), because there just aren’t enough knowledgeable people to form a quorum for quality discussion. But it’s also true in many of the hobby/interest discussions, simply because there aren’t enough people to where good discussion encourages more high quality discussion in a feedback loop.

Partially. I think it’s a good drop in replacement for:

• Anything technology oriented, from software to hardware to what different open source projects are up to, to what tech corporations are doing, and various discussions around ecosystems (the internet itself, specific services like Discord or Reddit or LinkedIn, app stores, social networking, etc.)
• Funny memes or other humor

It’s got pretty good coverage of certain topics:

• Politics, at least on specific sub topics
• Science and specific scientific disciplines

It has a few pockets that work for very specific things:

• Specific TV show or movie franchises (looking at you, Star Trek)
• ADHD or neurodivergent support/advice
• Noncredible Defense is actually here. Love it.

And it’s just missing a bunch of things I loved on Reddit:

• Sports, especially the unique culture of the NBA subreddit
• Other specific interests in television, film, music, or other cultural interests.
• Local things in specific cities
• Finance and economics stuff
• Lots of specific interests/hobbies are missing, or just aren’t as active.
• Advice/support for career/work life, especially specific careers (in my case, the legal industry and life as a lawyer)
• Advice/support relating to personal relationships, from parenting to dating to very specific support forums for things like divorce or cancer. Even what does exist here is disproportionately neurodivergent, so the topics of focus seem to be pretty different than what would be discussed in other places.
