>>I suppose my choice of "expulsion" was more in context of cyberwriting--email, ng postings. Something about clicking 'send' feels like "ejecting" something out to the world. Those kinds of missives tend to be opinions and/or attempts at persuasion, and evoke a "hurling" image to me.<<
Ah, I see what you mean, Wanda. The word "launching" also comes to mind. It is interesting how sending off an email or ng post does have that definitive, do-or-don't, "off it goes," "too-late-to-change-your-mind-now" feeling that's associated with the "send" button.
