I left reddit totally when I made my account here. Lemmy has been great, but it's not a full replacement per se. Most often I've just decided I can live without the niche reddit content. Lemmy has plenty of its own content, and it's enough for me to fill that "hole".

As I'm sure many are aware, reddit has addictive qualities that aren't always serving your best interest. Just because there's a subreddit for r/breadstapledtotrees doesn't mean you should dedicate time out of your day to look at it. All the important discussions to me have mostly moved over here, and all the people who are posting and commenting on Lemmy have a much much higher level of aptitude on these topics than redditors (I like that you can go into a random meme community on Lemmy and pick a fight about filesystems).

We still need to create and fill a lot of niche communities here, but Rome wasn't built in a day and we're making great progress here in just a few months. Lemmy feels viable and sustainable and I think we're past the hard part of gaining critical mass and making daily Lemmy use a habit. My call-to-action would be to stop searching reddit for answers to things and start posting those questions on Lemmy. There are so many smart people here waiting to infodump their experience onto you.
