Frequency and Informality Makes Ullman's Email More Personal

One way in which I could compare myself to Ellen Ullman in regards to email is its use for intimate conversation. While Ullman frequently used email to talk with her "lover," I rarely use email to talk to friends and family. I generally use email for more formal purposes, rather than recreationally or for chatting with people I know well. Most of my email is correspondence with people that I don't know as well, such as professors or GSIs. For this reason, I can't relate to Ullman's use of email, and certainly can't imagine falling in love with someone who I had only talked to online. I supposed that Facebook (which didn't exist at that time) is my replacement for Ullman's email, since I use this to stay in touch with friends and have more personal discourse. Still, I can't fathom developing such strong feelings for a person as Ullman did through an online connection.
A second way that I differ from Ullman is the frequency of my email or Facebook use. While she was on the computer much of the day because of her job, I only use the computer a couple times per day. This enabled her to check her email very often, while I have many fewer opportunities. This likely contributes to how often she emails, and the strength of the connection she feels with Karl. Also, the frequency of her emails and the shorter time between them would make her threads seem more a like a conversation than my emails or wall posts. Perhaps if I had the ability to check my Facebook and email more often, I would better understand Ullman's feelings.
