Thank you, I'm aware of that. But that still requires a person to be a pretty obsessive user of this site. Unless I have a lot of free time (like today), there's no way I can go back and check every single site where I've left comments and see how my comments are doing. At least LW aggregates reply comments to my input, but that doesn't solve the bigger problem of me having to come back to LW in the first place.

It's also worth noting that this comment interface is difficult to use in many places with slow/bad connections, like, you know, the entirety of Africa. Right now I'm in an amazing internet café in a capital city; but when I'm at home, I sometimes can't comment at all because my connection is too crappy to handle it. I don't get the impression that LW is very concerned with diversifying its userbase, but if it is, then a more accessible interface for slow connections would be important.
