The differences are well summarized on their /about page.
I find both HN and Lobsters valuable for different reasons, but and the differences that stand out to me are:
- Tries to be more purely technical. Generic political or business links are flagged or removed.
- Aggressive marketing/self-promotion is moderated: If you join, post three links to your own blog, and nothing else, expect someone to call out if you post a fourth. I know HN does this to some extent, but it is very explicit on Lobsters.
- Not "news", not necessarily about recent things. Project/language releases even have a "release" tag so you can hide them systematically. A ten-year-old article explaining some library internals is just as likely to come up.
- Instead of "downvotes" there are "flags", which requires choosing a reason. Ideally encourages people to pause and think, instead of scrolling and clicking a down arrow 20 times in a thread.
- Weekly community threads of "What are you working on this week?" and "What are you doing this weekend?" which is nice for a smaller community.
