I know that the reputation requirements for various privileges are kept lower on SE's beta sites.
My suggestion is, shouldn't the threshold for acquiring badges be lowered too for such sites? I'd quote here what SE refers to as a beta phase of a website.
This is the actual, live site set up on a "probationary" basis to see if people use it. It is very important to participate early. The earliest questions set the tone and topic of the site for a long time. This is also the time to spread the word via Twitter, blogs, and email far and wide.
So, while we can reduce the threshold for badges such as Excavator or Deputy badge, we can; on the other hand; increase the number of visits for Announcer badge.
What are the views of other members about this?
