When I moved from Digg to Reddit, I used to check back on Digg until eventually the content on Reddit became better than on Digg. The same will happen here.
It took me probably less than a month to completely stop checking Digg altogether. Reddit's decidedly less slick interface had me confused and the content wasn't as easy to digest as with Digg, but it didn't take long to completely abandon it. That was like ten years ago.
I guess a small point I'm trying to make is that you shouldn't feel "shame" for checking reddit. You'll adjust and learn to love whichever alternative you choose
I am a longtime lurker going back ten years. I probably could count the number of posts on two hands. What worries me is being able to make the switch to the fediverse as a concept. Just hoping Lemmy is the right choice for now.
