This has been my mindset as well. This is an awkward phase where Reddit alternatives are still being built out and millions of people are trying to find their home. Once the dust settles and communities build up, I hope to use the fediverse as I did site:reddit.com.
But for now, I think its okay to get information from reddit and bounce right after. Depending on what you're looking for, ChatGPT does seem to be a decent alternative to both Google and Reddit at the same time, though.
I wish I had an answer, but I will confirm this has happened to me multiple times as well. Im a mobile user, so I dont know if it's specific to mobile or not.
Either way, I havent been able to deduct why this happens. After refreshing it usually seems to go away though.
