Typing quirk

A typing quirk is a systematic method of typing, in almost all cases deviating from the standard usage of punctuation and capitalization, though grammatical rules are generally upheld. While the kids do not consciously choose their quirks, in the culture of the trolls, quirks are highly institutionalized, commonly going as far as using emoticons that more accurately represent the user's personal appearance, substituting letters in a fashion that convey aspects of the user's personality, and other varieties of personalization. The degree to which a person can control his or her quirk is variable and depends on the individual.

Quirks are commonly carried over into written text, though they may vary from the standard online usage due to the different medium. In troll culture, seeing writing in a given troll's quirk is considered validation of identity as good as recognition of handwriting.

 * Aradia
 * None. Never uses caps lock for emphasis.
 * Occasionally uses one or three exclamation marks. Uses no other punctuation.
 * Substitutes 0 for the letter o. After ascension uses regular Os.
 * 0_0 is the only emoticon she uses, except for 0u0 (once). Uses standard :) and :( - style emoticons after ascension, as well as using O_O rather than 0_0. Infrequently uses :D though this is probably to make people uncomfortable.
 * After becoming Aradiasprite, she occasionally ribbits, and retained this quirk after becoming Aradiabot. It is not known if she has retained this quirk after her ascension.
 * Before her death, as a ghost, as Aradiasprite and as Aradiabot, she is capable of using capslock as well as an occasional exclamation point. Exclamation points also appear in her speech before her death. After reviving and ascending, she no longer substitutes 0 or exclusively uses 0_0.
 * Tavros
 * Inverted. The start of every sentence is lowercase (and after every comma), and
