The subsite's logo is ER, which I know as Emergency Room, is that joke on purpose?
All of the beta sites have the same basic logo with a two-letter abbreviation added to resolve ambiguity.
When the site graduates from beta, the design will include a logo made specifically for the site.
I've seen E&R used as an abbreviation in several places by several people. I think it
- Is easier to pronounce (You don't try to read it "uhr"),
- Is more iconic, and
- Distinguishes us from the medical term.
I'm not trying to say that the image needs an ampersand to avoid issues of mistaken identity. I hope that any legitimate emergency room logo wouldn't be so sketchy...
