To be honest I don't think we are ready for that level of scrutiny. I would imagine if he were to agree, he would do research first, and the Fediverse has a lot of unanswered questions for the mainstream person.

Can the Fediverse sustain users, both in usability and costs (see also "Can we keep up with user growth")? How will NFSW moderation work, since so far I see most instances saying it won't and just shutting down that vector of work and questions? How does regulation or working with authorities look like on the Fediverse (this is antithetical to most Fediverse goals, but for main stream people a normal question)? How will user verification work for celebrities or important figures? What are the ethical consideration to support devs, like the lemmy devs, with controversial opinions?

Some of these are whataboutism when comparing to Reddit. Some of these just stuff the average Redditor and Fediverse user couldn't care less about, or frankly don't want asked, but these are top questions I would expect a liberal journalist to be asking, even if they are generally anti-corperate and pro-grassroots.
