This traffic isn't from typing a misspelled word into a search engine. The "run-up" was too fast. It is likely another site posted a link to
YF in conjunction with some information related to Athena or the owner.
I can tell you the viewers are not boating oriented, because there was no surge in new members. Most likely, they were just curiosity seekers. Although it sets an online record for
YF, the quality of the traffic is what's important.
