1) Journals must pursue interoperability with the other online tools that are shaping the techne of scholarly practice. (Yes, they're completely out of sync.)
2) Journals have opportunity to reframe their role in the academy as curators of the noise of the web. (Excellent. See it as an opportunity. And they can deliver a lot of value this way.)
3) Electronic journals will have the opportunity to expand their curatorial mandate to include different forms of publication. (The author mentions "a twenty-minute audio segment, a selection of maps shared on SlideShare, or a video segment of a conference paper shared on YouTube" as examples. I agree that, "properly curated," these can advance the state of a discipline just as much as the current article form.)
4) Against exclusive publication. 5) Broadening the criteria for participation. 6) The reconsideration of timelines.
Conferences and journals that have turned into tenure-case circle jerks are also not very valuable outside of those circles.
The big issue is who pays lead editors, though. Typically (at least in my field) the major journals have an institutional affiliation with a university, and the editors are professors at the university who receive a stipend and reduced teaching load in return for putting in a stint of a few years on the journal masthead. I've never asked too closely about the funding for these arrangements, but I have to imagine it comes from the universities themselves.
The question is: how do you convince the universities to do something similar, but not for a journal with a hundred year history in the field, but for one that is beginning right now and which follows a different format like the one espoused in the link? The two solutions are major institutional change among the administrators who fund this stuff, or finding a new model for paying editors. Based on my experiences in academia, I think the latter has a better shot, but it's still unclear how things will go.
In any case, these journals are run mostly by donations (donated time to review and edit, donated resources, paypal accounts, etc...). What is really interesting here are intentions: a platform to build fame and gain tenure, to disseminate results, or to nurture a fledgling field?
