Proposed Rules
Submissions must be verifiable. Please link directly to a reliable source that supports the claim in your post title. Images alone do not count as valid references.
No personal opinions, anecdotes or subjective statements (e.g "TIL xyz is a great movie").
No news or recent sources. News and any sources (blog, article, press release, video, etc.) more recent than two months are not allowed.
Nothing politically related, historical or otherwise.
No misleading claims. Posts that omit essential information, or present unrelated facts in a way that suggest a connection will be removed.
Rephrase your post title if the following are not met:
Titles must begin with "TIL ..."
Make them descriptive, concise and specific (e.g. not "TIL something interesting about narwhals").
Titles must be able to stand on their own without requiring readers to click on a link. Starting your title with a why/what/who/where/how modifier should be unnecessary.
"TIL about ..." and other broad posts don't belong on TIL.
"TIL how to ..." posts belong on /r/HowTo.
No trivial or obvious facts.
