There are simply some communities I can’t find on Lemmy. For example, I use subreddits based on admissions to specific colleges that would never be able to function on Lemmy due to its size. I’d much prefer to abandon Reddit altogether but the information I need is usually only there.
I don’t think I could do that, I would be compelled to comment. But I do still see Reddit in search results for problems I’m researching and the answers are often useful. I will be happy the first time I see a Lemmy result.
There is a search engine for Lemmy https://www.search-lemmy.com/
Not ideal that it’s outside of your preferred search engine, but it’s something.
It isn’t quite there yet but https://trystract.com/ gives some Lemmy results. It’s a beta, hopefully it develops further. I have no affiliation, I just saw it mentioned in Opensource.
