Weeks ago I pinned my first websites using the Push Pin while browsing with IE10-Metro.
I pinned "Google" and "Eight Forums"
I was greeted with a bland colored tile with an off white "e" as an icon for those sites.
Somewhat of a non-"START"er
Nothing to differentiate one site from the other, other than the Title.
I was quite surprise that some days later I pinned some other sites.
WOW. Site specific Icons and site specific coloring for the Tile.
So, the questions are...
How does a site 'tell?' the Metro browser how to color and iconize the pinning?
Why is this sites pinned icon/color a plain jane?
I don't really NEED an answer, I was just curious about what comes into play in determining those parameters.
