I could see my comments made from my Android phone when on my phone using Chrome (v 18.0.1025469) but I couldn't see them from home on OS X 10.7-ish and Win 8 both using Chrome (v 27.0.1453.94 on Win 8) . It was as if I had two separate accounts.
Recently the comments seemed to sync up but this odd comment segregation had been going on for weeks if not months.
Edit: Back now
I can also access them from the HN2 app for Android on my Incredible.
(ironically though, anyone who can't use them can't comment here to inform us of that fact)
No issues here, though I did have issues yesterday with submissions on HN.
It's optimized to read once, and fire of some inane comment (like this one), because by the time you come back to a topic, everything has shifted all around so you have to re-read every comment. It's terrible.
Edit: Back to normal now
