Yes, that is the dash. I think we are using it mostly without using xhtml and don't recall Matt Cutts mentioning that aspect. Also, we basically never use the www with any pages, links and sites since we decided to go nearly 100% with non-www several years ago. I also think Matt said the index.html (or whatever index file name such as .htm and .php) should be used in the url (but not positive). What issues would all of that cause?
