I do not enjoy real-time conversations. I have difficulty organizing my thoughts into the words I want and thus am often delayed in responding, which leads to awkward pauses and disjointed conversations. Texting and online conversations allow me to take my time in responding as well as work through drafts before finalizing my responses. And, as others have responded, those modes also remove the awkward physical/gestural/tonal qualities of real-time conversations.
