Pubpub has certain advantages - supports rich media, does away with the page limit, has some citation handling. Those things are ok.
The disadvantages however loom large, the biggest one I see being that we’re tying the entirety of our published output to a commercial platform. I’m not sure this is a wise move - I am not confident that Pubpub will be around for as long as NIME could be. Other than that the reference handling wasn’t that good and made everyone very prone to duplicating references, something that bibtex solved a very long time ago. I also thought that @andrew’s point about these publications not looking like academic publications is also an excellent point; if we want to be more outward-facing, then we should think about what it would mean to be relevant and credible to those outside our own community.
Ultimately I don’t see how Pubpub contributes something vital to NIME that a well-designed latex template couldn’t. The only really tangible improvement this year was moving to word limits instead of page limits, and excluding references, but that had nothing to do with the publishing platform.
