She's now getting much better at collecting her thoughts and presenting a cohesive message. My friends have exhibited a similar evolution with email usage. I am conscious of the words I use in conversation, just as in drafting a letter. I am deliberate and exacting with my words whenever possible. I've become so unaware of my vigilance in email that it has begun to affect the ways I communicate in general.
Email is so unlike traditional correspondence.
Paper letters and postcards have an inherent quality of definition. The historical legacy of correspondence is such that you usually only sent one letter, and you tried your best to get it right the first time. In that letter you would make an attempt to pack as much information as possible. I guess this is mostly because it's quite impractical to send a follow-up letter. But email allows you to conveniently send any number of messages, of any length.
