Almost negligible on L2. It's crazy! Although I prefer Hive because of the better user experience. Maybe the merge will change that for ETH. In any case, L2s are there.

I love Hive too. I am emotionally attached to it (I joined Steemit in 2017). It has also a great regular user base.

But for mass adoption and integration into RL I would place my bets on ETH. They invented smart contracts, nfts, ... right? Although Hive can be an important player too. Let's wait and see.
