First of all, the new update is looking good.
I have a small question or a comment on the front page.
If I understand things correctly then the actual frontpage shows only articles from the current issue - currently four of them. The older articles are found in the Archives.
I don't know but completely exchanging the articles so quickly seems, well, wasteful. It's easy to overlook the Archives page and it would be a shame to let the previous articles be forgotten so soon.
One possible solution would be to let the front page grow longer. I wouldn't see anything wrong with that but I guess it depends on how important you consider a clean separation between the individual issues. A different solution would be a post before (i.e. at the bottom of) a new issue that is a kind of digest of the previous issue or some other form of more prominent link.
