What do you think should happen in this scenario? Matt Cutts is aware that a reasonably high-profile site is not being indexed properly. Should he just ignore that?

I think it's particularly good that this is being done publicly, too. There's billions of sites out there and Google can't provide this for all of them, but since they're doing it publicly others can learn from it and know how to address it.

If Matt was artificially boosting HN's ranking that would be disturbing, but they're fixing an indexing issue.
