Think about things from the point of view of someone who has never used Reddit or the fediverse, but you've heard about them both from recent news articles and want to see what they are about.
Reddit:- You Google Reddit and your first result is Reddit.com. You click the link and are presented with the front page. You from scroll from a few hours and end up signing up and staying.
Lemmy:- You Google Lemmy and your first result is a wiki article for Lemmy Kilmister... Your second result might be join-lemmy.org, which you're smart enough to realise it's probably more likely what the news is about.
You click join-lemmy.org and are presented with a page of information about the fediverse, links to set up a server and pictures of code...
There is very little chance you're going to investigate further.
If we want the fediverse to replace Reddit then either
A) Lemmy needs to improve its initial impression and Search engine optimization
B) We should be promoting a different platform with a better initial first impression.
I'd recommend kbin personally as it gives the same sort of experience as Reddit from the initial interaction.
User experience is an extremely important part of on going growth. I feel like even with the migration under the circumstances, the onboarding and learning curve for new users is very difficult on kbin or lemmy vs reddit or other mainstream socials.
This may seem trivial to motivated users to go through the setup and learning required but for further migration and adoption the UX definitely needs significant improvement. I haven't seen or heard much being said on this subject regarding the fediverse in a serious way.
Products that are already simple to understand and use, spend time refining and reducing friction for growth and retention. I know these products are in their early stages but while the fediverse has its pros, I am concerned that the rate of improvement of UX for the fediverse will be very slow. But I am hopeful that people will keep pushing to make it better.
for YEARS I refused to use the site which should not be named because I hated the UI. RIF is literally the only reason I explored outside the group I joined for.
