Electronic Writing

I have no experience with writing a blog but I do use facebook and e-mail quite often. I'm not a fan of a lot of electronic writing, I'd rather talk to a person or write something down on paper where it is actually tangible. I usually change my mind several times when I'm writing so I hate going back and deleting something I've written though I end up doing that more than I want. I do think my writing changes when I use an electronic medium mostly because I usually know who I'm talking to very well (e.g. facebook) or I barely know who I'm talking to (e.g. e-mailing a prof). For the first case, I write how I would say it, leave out punctuation and grammar and use a ton of abbreviations and symbols. For the second case, I tend to write very formal and double check everything at least twice like a I am right now. I usually don't use conjunctions and I make it sound much more eloquent then I probably would if I asked them to their face.
