I personally use the One Dot Leader Unicode on Twitter in place of the standard period when I make announcements of domain names being sold/acquired in tweets but wish not to have that domain name become a hyperlink. I had long paid attention to the fact that I did not wish to make every domain name that I talked about a hyperlink but never really paid close attention to the appearance during the process of stopping the hyperlink. Since most of the newly acquired domain names I announce do not resolve yet, since they were just purchased, the hyperlink is useless...
