In the spirit of Valentines Day (tomorrow, the 14th), Google made a blog post with some survey results--

Love is in the inbox
   * 1 in 3 survey respondents noted having emailed a love letter
   * Young people indicated they were less averse to showing their affections over email than older adults: only 14% of 18-24 year olds considered email love letters bad behavior, compared to 43% of respondents over the age of 55
   * Men were more likely than women to have asked someone out via email (26% versus 16%)
   * While 31% of 18-24 year olds thought asking someone out on a date via email was poor form, 42% of respondents aged 55+ felt the same way
Breaking up is hard to do; some get help from email
   * 1 in 3 male respondents considered "break-up emails" neutral to good email etiquette, whereas only 1 in 7 female respondents agreed
   * 8% of men and 6% of women said they had broken up with someone over email
