Posts vs Comments: Two Very Different Signals

Most accounts are roughly ninety percent comments. Combine posts and comments into one "activity" figure and the posts vanish into rounding error — along with most of what distinguishes one account from another.

The two behave differently enough that merging them is usually a mistake.

Posts are declarations, comments are responses

A post is initiated. Someone decided a subject was worth raising, chose a community, and wrote a title. It carries intent.

A comment is reactive. It exists because something else did, and its content is shaped by what it replies to. A comment saying "that's not how it works" tells you almost nothing without its parent.

For research this means posts answer what does this account choose to raise, and comments answer how does this account respond to others. Different questions.

They are moderated differently

Posts face more scrutiny. Most subreddits have rules about post format, flair, titles and topic, enforced automatically. Comments face fewer constraints and lighter enforcement.

So a low post count in a community may reflect its posting rules rather than reticence. Someone with two hundred comments and no posts in a strictly moderated subreddit is participating fully — the format simply is not available to them.

They are archived differently

Posts are richer records: title, body, URL, flair, comment count, domain. Comments carry a body, a parent and a link.

That asymmetry shapes what analysis is possible. Domain analysis only works on posts. Thread structure only works on comments. Score distributions differ so much between the two that pooling them produces a meaningless median — post scores run higher, since a post is visible to everyone browsing while a comment competes within a thread.

Compute score statistics separately. A pooled figure is dominated by whichever type is more numerous, which is comments, which means it is a comment statistic wearing a general label.

What the ratio does and does not say

A 7% post share is a real, checkable fact about loaded records. It is also frequently over-read.

It does not indicate confidence, seniority, expertise or personality. It reflects which communities someone frequents and how those communities work. Someone active in a discussion-heavy subreddit will comment more than someone active in a link-sharing one, without any difference between the people.

Where the ratio is genuinely useful is in change. An account that posted regularly and shifted to comments only — or the reverse — has changed how it participates. That is a pattern worth noticing, and it survives the caveats better than a single ratio does.

Practical guidance

Report them separately, always. One combined number hides the distinction that carries the information.

Do not compare post counts across communities without accounting for posting rules.

Use posts for topic questions, comments for interaction questions. Posts show what someone raises; comments show who they talk to and how.

Watch the sample. Posts are rare enough that a hundred-record load may contain very few, and conclusions drawn from six posts are conclusions drawn from six posts.
