I'm not sure if this will be relevant to its longer-term success, but I notice that the word "Mastodon" seems to be very easy to misspell -- In the comments here alone I already find "Mastadon", "Mastadoon", etc.
> First attested 1813, from the New Latin genus name Mastodon (1806), coined by French naturalist Georges Cuvier, from Ancient Greek μαστός (mastós, “breast”) + ὀδούς (odoús, “tooth”), from the similarity of the mammilloid projections on the crowns of the extinct mammal's molars.
No one is thinking about the history of the word, in fact I personally was wondering why they chose an elephant as their mascot until I remembered what a Mastodon was.
