Is there any requirement that you can work on a "show HN" project for less than 24 hours? Were you prohibited from touching it afterwards? I don't understand this argument.
If you create something that is only working on Chrome, at least put "Google Chrome only" in the title, otherwise this is a broken application that you've just posted for the world to see.
You failed to answer my question, but I will answer yours.
1) No, but it seems most of the world liked it enough to upvote it.
2) No, but it was a low priority for me.
3) I did not know it only worked on Chrome, due to the time constraint I was under.
