Given that Stack Overflow is close to its fifth birthday as a public site, has any thought been given to a 'semidecadian' badge for people who have:
- been registered with the site five years (a semi-decade, hence the name),
- scored more than N points per year on average (where N might be 1000).
The idea behind 'average of N points per year' is to allow slow starters to gain the badge eventually, rather than ruling them out in year 1. The details are obviously subject to tweaking.
This might be a gold badge (the platinum version would be the decadian badge, with a larger value of N required — and no-one eligible for another 5 years or so).
These would complement the current Yearling badge (which is silver).
