Lobsters

Lobsters is a small, invite-only link aggregator for technology, where submissions are voted on and discussed by experienced developers.

Posting is free but requires an invitation and an account, with moderator rules rather than editorial review. Self-promotion is tightly policed.

No DR or traffic figures are published, and volume is far below Hacker News. This only works for genuinely technical, discussion-worthy work — a marketing post will be flagged, not upvoted.
