A great use for reddit is the ability to search posts and opinions about any niche topic. Will that be possible with Lemmy as it grows? Will I be able to Google “instant rice Lemmy” and get a comprehensive tier list of each brand?
I imagine search engines will have trouble with all the different instances(?). EDIT: Especially with instances that don’t have Lemmy in their name, I don’t think search engines would return them for Lemmy searches?
On reddit you may have the same post twice but the comments will be different. On Lemmy, you have the same post on every federated lemmy with the same comments on all of them. With the way google handles websites right now, if they started including Lemmy instances in their web, it end up having hundreds of the exact same result each hosted on a different lemmy instance.
Edit for clarity: All lemmy sites share their data with each other unless they explicitly stop doing so (defederating). This is why I can respond to your comment even though I’m on kbin.social and you’re on lemmy.world
