Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.

Rule summary

  • Nothing NSFW: Please post and comment appropriately.
  • Be respectful: Don't put down other users.
  • No advertising or spam: This also applies to low-effort posts. Spam will not be tolerated.
  • Self promotion must go in the self-promotion thread: If you made a for-profit system and/or it reads like an ad, put it in the monthly self promotion thread, stickied at the top of the subreddit. If you continue to post self-promotion, you will be banned.
  • No AI Slop: Any posts that is created by AI will be removed. Continuous violation will result in a ban.
  • Posts must be about PKMS: Posts must relate to Personal Knowledge Management Systems

Works well

  • A detailed, human-written post about how you set up a Zettelkasten system in a specific tool and what it changed about your workflow.
  • A question about how others handle a specific PKM problem, like linking notes versus tagging them, that invites real discussion.
  • A walkthrough of your personal knowledge management setup that focuses on the method and the thinking behind it, with no product pitch.
  • A single, well-crafted mention of your tool inside the monthly self promotion thread, following whatever format that thread expects.

Avoid

  • Posting any for-profit system or tool as a standalone post instead of in the monthly self promotion thread.
  • Using AI to generate your posts or comments, since the community bans AI-created content.
  • Putting down other users or posting anything not safe for work.
  • Submitting low-effort posts, since the rules treat low effort as spam.
  • Posting about topics that have nothing to do with personal knowledge management systems.

What r/PKMS Is For

This community is for people who care about personal knowledge management systems, which means the methods and tools used to classify, store, and organize information from daily life. The description mentions objectives like improving memory, recollection, creativity, and idea creation. It references methods like the Zettelkasten system and tools like Logseq, and notes that mind mapping can also count as PKM. Based on the rules, the people here want real discussion about these systems, not pitches.

Rules That Matter Before Posting

The rule called 'No advertising or spam' is the first gatekeeper, and it explicitly covers low-effort posts too. The rule 'Self promotion must go in the self-promotion thread' is the one that decides where your product mentions live, and it comes with a ban warning for repeat offenders. The rule 'No AI Slop' is unusually direct, so anything that reads as machine-written will be removed. Finally, 'Posts must be about PKMS' means your topic has to clearly connect to personal knowledge management systems or it will not survive.

What To Post

A good post here is a genuine, human-written contribution about how you personally use a knowledge management system, what method you follow, or what you have learned from organizing your own information. If you are a founder with a tool to share, your only safe path is the monthly self promotion thread that is stickied at the top of the subreddit. Outside that thread, your post should read like a real person sharing a real workflow or asking a real question about PKM, not like marketing copy.

What To Avoid

Avoid any standalone post that promotes a for-profit system or reads like an ad, because the rules say that belongs only in the monthly self promotion thread. Do not post AI-generated content, since the rule 'No AI Slop' says such posts will be removed and continued violations lead to a ban. Avoid low-effort posts, because the spam rule explicitly includes them. Stay away from anything not safe for work, anything disrespectful to other users, and anything that does not relate to personal knowledge management systems.

Common questions about r/PKMS

Can I post about my PKM tool or app directly in the community?

No, if it reads like an ad or you made a for-profit system, it must go in the monthly self promotion thread stickied at the top of the subreddit.

Can I share a non-commercial PKM method or workflow I developed?

Yes, as long as it genuinely relates to personal knowledge management systems and does not read like an advertisement.

Are AI-generated posts allowed if I disclose them?

No, the rules state that any posts created by AI will be removed and repeated violations lead to a ban.

Can I include links in my posts?

The rules do not specify, but they do say spam will not be tolerated and low-effort posts fall under that ban.

What happens if I keep posting promotional content after being told to stop?

The rules say continued self-promotion outside the stickied thread will result in a ban.
