Like the migration from Twitter to Mastodon, I would like to find that Humanities Commons - in my case: https://hcommons.org/members/stevemccartyinjapan (with nearly 10,000 downloads) - does better than ResearchGate - https://www.researchgate.net/profile/Steve-Mccarty (31,600+ reads) - or AcademiaEdu - https://wilmina.academia.edu/SteveMcCarty (31,500+ views) in connecting repository content with researchers and other readers, interactively. Perhaps browsing is more convenient than downloading, and commercial outfits have a stronger imperative to connect people.
Humanities Commons has many genres to select from, and I have uploaded content in 24 academic and creative categories. Successful research grant proposals seem like another possibility, and a research diary format would suit our India-Japan project on humanizing online educational experiences.
