The vast majority of what I produce isn't for a HIVE audience. My ttrpg content/reviews are shared on BlueSky because that's where my audience is - and even though we don't get referral data anymore in our analytics I can definitely tell that folks from outside the Hive ecosystem are coming and reading. Similarly, the blog posts I tied to my series of Vampire Survivor walkthroughs still get about 50-100 views a month and I posted those... a year/half a year ago.
I don't know if any of the passive pulls to the blog have turned into signups, but getting folks here definitely is something I've been keeping an eye on for the last year on my own accounts.
