Yea it is. We have been niche for a while now. Even a small scale adoption will push numbers here a lot!
In total there is around 10k MAUs on all the Hive frontends, making posts or comments. What's interesting is that in terms of MAUs, the numbers for account making transfers of HIVE/HBD is bigger and it is around 15k. Then next are votes/curation, and accounts making custom_json, aka games are into the 100k MAUs.
