Lemmy is a very promising foundation - I think more accessible than Mastodon, which also has a great community but the way posts are organized in Lemmy seems more intuitive - although the process to add a community in Lemmy (searching the URL) is kinda clunky and the UI has some issues, we can knock the burrs of the software easily enough -- but just based on seeing the uptake from Reddit, the basic idea of Lemmy seems like it could be the home run in terms of getting people (at least the smart ones) out of corporate-run social media sites. This is very different to the twitter -> Mastodon migration which was pretty chaotic - Lemmy seems (somewhat ironically) well-organized in comparison.
