A bit of both ('reader', meaning a human).  I rarely originate styles, so it
must have been something I picked up from others' use in echomail over the last
26+ years.

It's a textual thing so I very much doubt there's any software link, but at the
same time it is a step beyond simple smilies and avatars.  It's meant to evoke
a memory or general impression of a situation, or perhaps even recalling a
musical piece to provide an aura.

Rock on...

Cheers,
Paul.
