What Reddit asked this week.

How to read these pages

Every page here covers one community over one week. It lists the questions people asked, the words that kept coming up across separate titles, and the posts that had drawn the most discussion by the time we saw them. The live page rolls forward every day, and when a week ends it is kept as its own page so the record does not disappear.

The figure worth paying attention to is the share of posts asking a question. A community where a third of the posts end in a question mark is one that expects answers, and that is where turning up with a useful reply is normal rather than intrusive. A community where almost nothing is a question is a broadcast channel, and the handful of real questions in it are worth more precisely because they are rare.

One caveat we would rather state than bury. We read the newest posts in each community every day rather than all of them, so the post counts describe our sample rather than the community total. Use them to compare a community against itself over time, not to compare one community against another on volume. The question share and the recurring words are not affected by this, because both are proportions within the sample.

For what each community is actually for, who posts in it and whether you are allowed to mention a product, see the subreddit directory. To search the same collection by keyword instead of by community, use the subreddit finder.
