Strange objects in antique shops, found during a cleaning session or dug up, "gifts" when moving into a new house, curiosities we see every day... if you don't know exactly what it is and need to find out to satisfy your curiosity, then you should take a photo and share it in the WhatIsThisThing subreddit. Each post is a new challenge, and there are more than a million people looking...
Of course, the story doesn't end there. Many people want to identify insects or plants, ask about problems in their homes (mold and stains are the most common topics), correctly read military decorations, recognize types of clouds, and more. Some of the posts are a real show, and force moderators to intervene. Others end up revealing very dark situations, as the user discovers they have more serious problems (someone tried to break into their house, they're being cheated on, they're being spied on, etc.).
How to identify objects with a photo
As always, throwing yourself into the jaws of a subreddit carries certain risks, but the community of WhatIsThisThing is very calm and respectful compared to other corners of the aggregator. If you've exhausted all your options and can ask a couple of questions in English, don't hesitate to give it a try. Maybe the answer is simpler than you imagine. Would you like to see some positive identifications...?
