I think the reason you're getting so many comments on this aspect of it is because a lot of people on HN have been through several rounds of the browser wars and many care deeply about keeping the web vendor neutral (especially in terms of the near-monopoly that Google has).
Whilst there's often good reasons to state that something will only work on Chrome - it's something that should probably be wrapped in a something approximating a mild apology:
"Whilst this might work on any browser that supports IndexedDB I've currently only tested it on blah blah" - that kind of thing...
