Computing-focused community centered around link aggregation and discussion
In the last year, I have joined https://lobste.rs which is relatively low-volume, but tends towards high quality. It is entirely tech / programming focused, and politics and such are not allowed. It is an invite-only membership, so you have to know someone who will extend to you an invite. Since their account is listed as the sponsor for your own account (forever), your reputation will affect your sponsor's. Not automatically, but if the site admins see a particular person inviting a bunch of yaboos, there will be some kind of consequences.
I too mostly don't use reddit for the mainstream subs, but instead of niche stuff like /r/RISCV and /r/rust.

Truly a developer’s best friend. Scout APM is great for developers who want to find and fix performance issues in their applications. With Scout, we'll take care of the bugs so you can focus on building great things 🚀.
Can anyone tell me more about Lobste.rs ?
