I've very recently started helping Zaka out with the blog, so there's the two of us on that at least (though I have no access to set up posts myself). For the most part there's rarely that much news that we shouldn't be able to keep it relatively up to date on that front, though I'm sure more writers wouldn't be a bad thing. However, if the blog is to be used for non-VN news in the future (like new episodes of podcasts) more people would definitely be needed as I don't have any interest on that front.
I'm nothing special around here and as such shouldn't really have a say when it comes to what the blog should and shouldn't contain, but back when I just started visiting Fuwanovel it was actually primarily to get VN news from VNAer and as such my personal opinion is that it should strive to be the best source for VN news online, be it translation updates, recruitment bulletins, translator interviews, etc. As a reader back then without any specific relation to Fuwanovel I wouldn't be interested in posts about new episodes of the community podcast. With that in mind I think those sort of community focuses belong more on Fuwanovels Facebook and Twitter feeds, while the blog should be the one-stop go-to place for VN news. But again, this is just my opinion as a person who didn't originally come here for the torrents but for the news. Whatever the staff actually decides to do I'm sure will be the right thing in the long run.
