I see a ![new](https://i.stack.imgur.com/zajGN.png) ![new](https://i.stack.imgur.com/zajGN.png) icon next to 'blog' in the footer. I was wondering how ![new](https://i.stack.imgur.com/zajGN.png) a post has to be for that to remain. I have viewed the post many times, and the icon has not gone away, so I assume it is not tied to a person't account.

I was just wondering how ![new](https://i.stack.imgur.com/zajGN.png) is ![new](https://i.stack.imgur.com/zajGN.png)? (Or, when will ![new](https://i.stack.imgur.com/zajGN.png) go away?)
