How do you feel about the massive influx of users?
A little bit worried. I am a recent migrator myself so this may a bit hypocritical, but I feel a lot of people will want to "redditize" here, just like how people tried with mastodon a couple months ago or (in a larger level), how people want Linux to become "another Windows".
These are not replicas, Lemmy doesn't work like Reddit, neither does it try to be, and that is by design, not a flaw. Things work differently, over and under the rug, and I think users should be entitled to doing some small effort to readjusting and have an open mind.
I'm all for UI/UX improvements, like most community projects, the front design part is more of an afterthought, and in that matter Lemmy has a lot to improve, but always keeping in mind what it is aiming to be.
For example, I am thinking in working on some simple browser extension to rearrange the UI in a way similar to Reddit's (nothing fancy, the upvote/downvote and collapse buttons locations, simple things). Maybe even some redirecting magic so if you open a link to another instance's community, it instead opens it in your current one, so you can still interact without having to go to your instance and search this one.
If anything, as a FOSS and federated content advocate, I wish this project nothing but the best so that one day we can escape the clutches of greedy companies.
