With all of the instances having different URL's, what's the best way to "google" a question and get Lemmy instance answers?
For example, I could search "best blender reddit" and browse tons of threads and gather advice. Is there an equivalent we can do in the future with Lemmy/Kbin?
why would you care where the answer comes from? if the answer is what you want, that is. if you want to jerk off about lemmy/reddit/facebook/whatever, just go to appropriate homepage and do your job.
you do seem to have some misconceptions about the world.
first one is that because something is on reddit, it is not "garbage blog content".
have you tried using google without "site:reddit"? it gives you results (what a surprise), some of them may be on reddit, some of them may be not. look at them and decide which ones seem relevant to your search. it is quite easy.
here is the thing. i wasn't trying to be funny. you, on the other hand, were and the best you could do is parrot thousand years old cliche, so if you want to worry about someone not being funny, i suggest to aim your focus at the nearest mirror, you pathetic clown.
