I'd like to read people's comments in the context of their previous comments. Other readers may be much better at this than me but I find it hard to index what people are saying against just a handle.
It would be great to see some more clues to people's identities appearing next to their names - not necessarily a photo but perhaps a snippet of who who they are / what they do (their about section perhaps). It doesn't have to be there all the time, onmouseover would be great but it would be nice to easily get that reference.
