Adding to the other response here -- it's great to thank your customers, and you wouldn't want to hide that you're affiliated with AgileBits. But please bear in mind that people reading HN are here to read a discussion.

A good guideline is just "does this add useful/interesting content to the discussion?"; if not, think very hard before adding it.

Plus from the HN guidelines: Please don't sign comments; they're already signed with your username. If other users want to learn more about you, they can click on it to see your profile.
