My understanding is this: Dash > underscore in URLs because underscores are hard to see in underlined links and SEs see dashes as spaces.
If this is true, what do they see underscores as?
I ask because I'm doing something right now that automatically uses underscores and not dashes (I don't think I can change it unless there's some funky thing with mod_rewrite).
Is it worth finding a solution to remove the underscores and use dashes instead?

not resolved
