HN suggestion: Add more context to commenters' identities

HN has an incredibly high number of good commenters but with the exception of people I know in real life or a couple of high profile cross-referenced commenters like patio11 I don't feel like I build up a mental profile of anyone else. I'd like to get more context for people's comments and to read them 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. I don't know what PG's stance is on this but I would love 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. What are other peoples' views on this?
