I've been making word clouds using words that include domain extensions that I have been pasting in from Excel like:
electricbrush.com
centrevilleplumbing.com
answermachines.com
adelaideproperties.com
bestcampuses.com
costoflivingbystate.com

After pasting, the tool is removing the ".", and listing "com" times the number of domains and stripping the domain extension from the coresponding domain name. This is something new, because it was not happening with the previous 6 word clouds I had created before.
