I tried it and liked it a bit. The problem for me was that it was very empty: posts about the same article had more comments in Lemmy than Digg. It also lacked many features that even Lemmy has. And, since everyone was able to create 2 communities, there were more communities than users. Most of them were created and forgotten, while others tried to get bigger with only 1 user posting everyday. The biggest/mainstream communities had less than 100k users each one. After some days, I joined Lemmy and never looked back.
