One of the best things about reddit was looking for answers or other users with the same problem as you, and since Google didn’t really help with that anymore and instead insisted on giving you business results, the best practice was to put your search terms in followed by ‘reddit’ and you’d find your answer.
If Kbin federates with the “seed” Lemmy server it’ll pick up the posts that way, but at the moment you’ll only be able to open links to Lemmy instances.
In the future I hope to have it working with Kbin and others as well.
