I think it's slightly more complicated than that: Azimuth is clearly a public outlet of some sort, but equally it's not a recognised conference venue. I know in my field you're told you can't submit work that has already been "published" to a conference (some people do, of course), so putting anything close to cutting edge here may "burn" that research. (I don't know how this works on the arxiv: I know theoreticians in various disciplines publish there, but I've seen less from data-based areas.)
