Please don't copy-paste comments on HN, and especially not someone else's. Copying lowers signal/noise and makes thread merging a nightmare, since we end up with duplicates.

If you want to reference what someone else (or you yourself) already posted, please do so with a link. Adding info about why you're linking to it is also welcome.

Edit: Actually it would be fine to quote from what you're linking to as well. This did lead to good discussion and I don't mean to interfere with that!
