If I wanted to find a particular subreddit for whatever, it was as easy as typing in the name of the show or hobby. And it linked to other similar / related subreddits
Or someone would link to another subreddit in a comment.
Here I'm having to sit and learn what an instance is and if the community I was in transfered over, and if they did where did they go.
It's turning away alot of the less tech savvy people.
Does it need to be as popular as reddit? I don't think so, anything that grows too big becomes a hassle and a problem.
But to grow it would need easier interface or ability to find/interact with other communities.
