Comment (by Ipstenu):

 If we're going down the 'allowing usernames but not blog names' UX route,
 then we need to factor in a notification.

 Like.. "Notice: Your username contains characters that cannot be used in
 your blog name. We have adjusted your blog name for you, but please review
 and confirm before you submit."

 A check box "Yes, I like this name" or something to make sure they know.
 Otherwise we'll have an unintended result (the blog not matching the
 username) as we've changed the status quo. Not saying it's bad, not at
 all, just that we have to remember to keep existing users used to
 multisite as informed as the newbies :)
