When subjects submitted their e-mail donation to CODE ALLTAG S+d , as a follow-up, a questionnaire was immediately sent to each donor asking for eight demographic variables and self-assessments of the donor, including gender, age, regional provenance, educational and professional background, language provenance and preferences, proficiency of writing and frequency of e-mailing.
writers of e-mails may face formal communication requirements much more often than authors of blogs, chats or tweets.
