I just earned the asp.net-mvc-3 badge. I was the 84th to get this one.
Today the URL
uses the badge Id to identify a given badge like this:
https://stackoverflow.com/help/badges/891?page=1
Id 891 points to asp.net-mvc-3.
Now I'd like to see who has the silver version of this badge. I tried changing the Id part to 890 or 892, but it's not sequentially. I'd have to guess the Id till I find the silver asp.net-mvc-3
badge.
A URL
format like this can solve it:
https://stackoverflow.com/help/badges/asp.net-mvc-3?type=silver&page=1
I think it's doable.
Another possibility would be to show the other related versions/types of a badge as links. For example:
In the bronze badge page, offer a link to the silver and gold versions.
In the silver badge page, offer a link to the bronze and gold versions.
In the gold badge page, offer a link to the bronze and silver versions.
