I’m sorry ahead of time for my disagreeing with you I feel so bad not being able to be supportive, but I do have an opinion on this.
I think it could become very tedious at some point to search a thread backwards for things you really want to find and look at again. Separate threads (monthly or otherwise) allow us to pull up a specific month or topic and have a chance to find something a bit quicker than endless scrolling. The search feature only works if you remember the exact terms used. I myself find scrolling backwards through endless lengthy threads to be frustration inducing and less appealing. This would be my opinion for any thread topic that could grow to thousands of posts.
I quite enjoy scrolling through the monthly food threads as they presently are, but I know I would miss most of it if it were all in one lengthy thread. I’d get bored and stop looking and then miss some wonderful ideas and inspiration. For some reason having small batches to sift through at a time makes it much easier and more appealing to me.
The biggest example I have is how the humor threads grew wayyyy too big, both of them. I love the humor almost as much as any other topic here, LOL. I love the smiles and giggles. But it’s torture to go back and catch up with how long it is. I was wishing it would begin a new humor thread at least for each year. Like 2023 Funnies and 2024 Funny Bones etc etc. just nicer to have less to sift through in a single sitting.
