What does the star button do on GitHub's gist section?
For example: https://gist.github.com/1372818
I have three buttons in the headline, they are:
edit - download - (un)star
With the last one changing from star to unstar as I click on it.
At first I thought it was an upvote system. But I can star my own code, and it doesn't mention some star appearing elsewhere.
The next idea was a favorites icon or a bookmark. I can select "starred gists" but the page came up even before I starred it.
The GitHub help didn't have anything about "star", and the search box is for searching in code and in pages - not to search the help pages of github::gist.
