I wouldn't worry about Lemmy having as many users as reddit in the short term. Success is not just a measure of userbase. A system just needs a critical mass, a minimum number of users, to be self-perpetuating. For a reddit post that has 10k comments, most normal people only read a few dozen comments anyways. You could have half the comments on that post, and frankly the quality might go up, not down. (That said, there are many communities below that minimum critical mass at the moment.)
Lemmy is now a real alternative. When reddit imploded Lemmy wasn't fully set up to take advantage of the exodus, so a lot of users came over to the fediverse and gave up right away. There were no phone apps, the user interface was rudimentary, and communities weren't yet alive. Next time reddit screws up in a high profile way, and they will screw up, the fediverse will be ready.
Lemmy has way more potential than reddit. Reddit's leadership has always been incompetent and slow at fixing problems. The fediverse has been very responsive to user feedback in comparison.
I follow damn near every community on lemmy that I followed on reddit. I follow 97 communities on lemmy with all communities active and none with 0 posts. I left reddit immediately and haven't looked back. All the news, whether political or tech related, I get from lemmy. I think people just haven't found the right communities. You have to put in some time to find them since you may have 5 or 6 with the same name. But, once you do, you should be good to go.
Comparing the two communities, reddit nearly always has way more quality content and news for me though for the time being. Often even with big news it's just not here on Lemmy at all. Many posts also have 0 comments and you just wouldn't see that on Reddit. Once Sync can create posts I will probably start x-posting more from reddit to lemmy for communities I am most interested in.
For now I think I will start browsing Lemmy and then visit Reddit for anything I missed. Keeping my posting and commenting over here mostly because I'd like to see this place grow.

It's not just you.
As constructively as I can put this, reddit has been building community and goodwill for many years. Lemmy has only recently become an option and it's done wonderfully in the short time it's had.
The challenge is the catch 22. People go where there is more content, they produce content there, and then there is more content there. There no vacuum, reddit didn't disappear. It became toxic and people apparently care less about avoiding toxicity than filling up on dank memes.
All I can say to that is we all need to be the change we want to see in the world. Adopt a Lemmy First mentality, and go to reddit only to pick up legacy slack. Continue the conversation from there over here. Link it up.
So, what do they want, lemmy people have to do over time in posting so the lazy people get what they expect from lemmy. If they are lazy, they can stay with reddit.
