For the past few years, I’ve been using Armadillo+Disqus for a couple of class blogs (around 40 students each) for low-level English speakers (mostly Japanese). But there are always several students who just don’t get the hang of Disqus registration/usage, and I’ve wasted a lot of class time going over it.
As an alternative, am thinking of using Poster Stack (very interested, but haven’t bought yet) together with Comments Stack (have). Would this be easier from the user’s viewpoint? Any comments appreciated.
