...do other people get frustrated with trying to communicate using email/MySpace etc?
I'm probably what you'd call "old school" in that I use "conversational style" in my emails (see http://mailformat.dan.info/quoting/bottom-posting.html) but I've come to the conclusion that there are a huge number of people out there who, when asked multiple questions in an email, are only capable of half-answering one of them.
Do I really need to send a separate email for each question? Won't people get pissed off with 5 emails asking one question each? Why aren't people capable of answering more than half a question in an email?
