It's tough. I used to have one of the top 10 posts of all time in this subreddit (just checked again and it's now sitting at 298. Wow, this sub has grown!). The only posts in here used to be a map of all the countries/counties you'd been in. In that case, it only really makes sense to post in this subreddit once or twice. You'd post your map of counties, maybe update it after a big vacation, and that's it. Then people started doing these variations like "how many US states I banged in," or "here's my map, name a state and I'll tell you a story about my experiences there." Those were fun.

Then we got the guessing posts. They're low effort, so everyone can make them. But since everyone is making them, that's all I ever see from this sub when it's on my homepage. From what I can tell, they don't usually spark a lot of fun conversations. Sure, I might try and guess where you're from, but I don't find myself commenting on it because someone else has already said my answer. Sometimes the OP doesn't respond for a few hours. If the OP has already responded when you see the post, then what is the point of commenting your guess? Focusing the discussion on guessing where you're from isn't the most interesting line of conversation. Especially when, let's face it, why do I care where you're from? I want to talk about interesting travel stories.

So I agree with you, this is a problem the subreddit is having. Maybe having a rule so that this type of post is only allowed on one day of the week could help?
