Exactly—that's why I ended the post with a list of examples.
I think they do that so they can copyright/trademark the names. You can't trademark a common noun.
That, and because the domain names like "dig.com" have been taken for a long time.
I hate it when people spell "c" words with a k. Like Krazy or Kountry.
Or 'Krispy Kremes'?
Or "Kidz (insert word)".
They do it for copyrights.
If they do it for any reason other than that, then it's stupid.
