I've been trying it out for the last week. I have my own opinions, but I'd like to hear others and see if we have common ideas on what is good/bad/indifferent about the Lemmy ecosystem.
Unfortunately not because this place simply isn't big enough to have the niche communities that reddit has. Not to mention the slow pace of the front page.
I've been using a combination of Lemmy and Imgur to replace reddit for the most part. But when I need a question on a specific topic answered by a real human, I still have to go to reddit. That's all I use it for now, though. There's also the fact that Imgur is no better than reddit. No 3rd party apps, and the official app collects all the data it can off your phone and sells it to Facebook. You can block the connection with the DuckDuckGo app, but that doesn't excuse the fact that this is fucked up. (FWIW, the Lemmy app Voyager doesn't sell any of your data. Unsure about others but Sync definitely does.)
