Well, like you yourself stated, it's time to hit the sack and get some sleep. I sleep to fight another day. I'm definitely a proponent of directing my comments, sarcasms, etc. directly to the person I am speaking with/about. That's just my personal style. No need to go through third parties, although it humors me, as it is a public forum, and everyone sees both the direct comments as well as the indirect ones, so nothing said is really hidden about anyone at any time. Good nite, sleep tight, and don't let the bedbugs bite.
Depends. That's what the "ping" page is for. For example. If someone said something about me later, I wouldn't see it, unless they pinged me to it, not pinging me to that post would be akin to talking about me behind my back. That's all it amounts to. Good night.
