A Bloomfield Hills or Grosse Pointe address automatically makes one think of large homes and spacious grounds. Similarly, a Warren address brings to mind industry and a blue collar presence.
Internet addresses evoke similar impressions.
AOL is the starting point for many people new to the web. An AOL address is usually a family address, with multiple family members sharing the same account. Prodigy also has family connotations. A free Hotmail or Yahoo address is often used by teenagers and younger folks with limited resources. They may have a net connection provided by someone else, but want the privacy of their own e-mail.
