I'm not sure of that analogy, but, when I throw out advice/suggestions/support I'm not exactly looking for anything in return. If somebody tells me to fuck off..............I fuck off. Or if I get ignored, then I say nothing further....usually. I'm not looking for alliances/sex/friendship.
Cyber alliances are like building a house on a sand dune, doesn't work. Sex......cybersex doesn't work for me. Friendships are nice, but, in cyberspace..what is a friendship? It has always seemed to me that cyberfriendships were at best a pleasant way to pass the time. Little to no expectations, there's no eye or physical contact, nothing to really form a lasting bond over. Just a pleasant pretext to wile away an idle hour.
Now having said that, I feel "friendships" with Callaway, PI, Drunkardswalk and others, but ultimately, it's not the same as a real life friendship.
Real life freindships are both emotional/physical/mental give and take in real time, 2 out of three on the internet ain't bad, but, it's just not the same.
But, comparing advice giving on a forum to a whore's ass is a bit of stretch, but then again, thats just you being you. Thats not a criticism, just a pragmatic observation.
