Is there anything to prevent you from making tons of different accounts (from proxied servers), so it looks like different people are posting the links when in reality it all comes from one person? This way you can also vote up your own links a lot...
Also, on the subject of reaching more people, may I suggest holding some sort of conference or symposium where various people have their papers read?
I don't see lots of activity from the ANUS metal community in the scholarly metal scene, but maybe that's also a way to go? If you're interested I'll be launching a discussion forum for scholarly metal discourse soon, you could bring your views to the table there (the site itself will take a neutral stance, the members do it themselves).
The scholarly metal scene is really taking off. In the future there will be an organization officially dedicated to the scholarly metal scene, I'm not involved but the website's being built. Times are a changin... (hopefully away from things like Reddit lol)
An extremely neat thing to consider is: what do you gain by writing articles for DLA? So the articles are all in the same place--DLA--but today with the internet's aggregatory capacities articles and papers are very easy to come by. If you submit texts to other places though, then you can really bring the conversation elsewhere. There are conferences about metal for example where you could submit papers, seems like something to do at least simultaneously as you work on Reddit, if not before Reddit.
