Hornbook

Hornbook seems to be the Alternian equalivant of Facebook and seems to be one of the social media Jerran enjoys spending his time on, the others being Trollkill and his blogs.

Functionality
Little is known about the funcctionality of Hornbook so far, but it is likely that it works in a very similar way as Facebook. Only known difference so far is the "Timetriangle", which seems to be the equalivant of Facebooks Timeline feature. According to Jerran, this feature is overly complicated and therefore heavily disliked by the public. However, he also stated that he understood it himself and found it effective.
