You never see creationists all swarming to these posts now do ya? Oh wait, they do too... Maybe we're ALL just one person! We must be a fast typer.
As for email, I referred to one I rec'd that tried to wheedle personal info out of me--looking for ammunition, under the guise of friendly interest. But posting histories are public property. If one cares to invest any time or interest, posting habits can be very revealing. Almost like an epistolary novel--which is why so many are attracted to online discourse. People bring pet frustrations and issues to the table--usually several competing issues, interests, and frustrations. After a while, you can read between the lines.
With evos, there's never that nuance or sense of discovery. Evis and Darwinhead, blah blah blah. "They're so ignorant, so stupid." It is significant that posters like you are one-subject characters.
Most string musicians aspire beyond the same ole E-chord.
