Do you really not see the problem? For Lemmy to face any hope of becoming mainstream your statement should be "less than 5 minutes".
Maybe that barrier to entry is a pro to you, and that's fair, but surely you understand the criticism that a social network should be usable without reading a guide, yes?
* This "less than one hour" I'm talking about includes really being familiar with the UI, concept and new terminology.
* I'm not really concerned if Lemmy becomes truly mainstream. I just find it funny that the crowd in HN of all places is so helpless that reading a FAQ and learning a few new names for basically old concepts is so bad that it needs to be constantly complained about. How on earth would these people have survived the pre-2010 internet?
* I did not need to read a guide, just a short FAQ and some fiddling around to understand the concept.
