Currently lemmy is like the speedboat next to the heavy steam boat of Mastodon etc. While lemmy is still dynamic and flexible and can introduce new features easily without scaring off its established user base, mastodon can not do such experiments so easily. Now, if lemmy gains more momentum in the fediverse and establishes features, which other services don’t have, it could really push innovation in the Fediverse further. What do you think?
It will if/when the userbase grows significantly. Look at the explosion of mobile apps the past few months. However, it ultimately depends on the lemmy devs, and how much time/effort they are willing to spend to drive innovation. The unfortunate reality is that commercialization and competition also drive innovation, and the fediverse is largely driven by passion and effort by people who have the capacity to do it without the expectation of financial gain.
