@warner Yep. It's good that both ways work, since it increases the chances of more people being able to use it. The editor also auto-fills the symbol in some cases (I haven't tested each posting interface yet).

This is one of the reasons why I support Manton's decision to stay away from rich text; that can be quite bulky and increase the opportunity for opaque errors, whilst simple text-based enhancements are often flexible with fewer opportunities of breaking the interface.
