When reddit was coming up, a big issue people had was it was too confusing with bad UI. People didn't know which subreddits to follow. Its very similar, theres just a whole other layer.
Just find a popular instance that is federated with similar instances. And making accounts are easy too, so just do it in two or three instances. Yeah it's a bit much compared to reddit, but it's very very easy.
In their defense, the reddit UI did suck and the webpage was barely functional for a very, very long time. How many years did it take them to get video to be even passably functional?
Almost every Lemmy interface is an order of magnitude better than anything reddit has ever managed to produce. Voyager is a pleasure imo.
