Lemmy has a different kind of potential compared to Mastodon and some of the other fediverse projects too. In my opinion Twitter's rise was created by corporations and media jumping on board with it. It was directly promoted in the media promoting hashtags and the like for the things they were doing. The issue is that these corporate entities and their supporters in the media won't jump on board with Mastodon as it's an anti-corporate project.

Lemmy on the other hand? A platform for communities? Communities existed before reddit in the form of forums and it was reddit that disrupted that market, killing off forums. There is no requirement for corporate involvement in the success of Lemmy and communities can emerge and succeed entirely on their own. As long as people dual-use it for long enough for reddit to repeatedly create catalysts that send users here there is an inevitable future.

In the meantime it's very important for people to make it good here on its own merit.
