Shneinu, sitting in front of a computer speaking to faceless people (who may or may not even be the gender we believe them to be), is NOT the same as saying hello to someone in the street. That being said, I will stick with my custom of being makdim kol haadom b’sholom. Far from a chillul Hashem, it creates a sense of ahavas chinam and achdus. And is that not what we need, to make a tikkun olam for the Churban?
Mosherose, I am so sorry, but you just sound so unyielding sometimes, but most especially with al tabeh sicha inyan. If I remember correctly it was a specific rov who said that and he was rebuked by Beruriah (?) for using too many words with her, given his personal viewpoint on sicha with nashim.
Your stated hashkafa is not one that is recommended between husbands and wives, I can tell you, or with other Yidden. If you truly believe a man and a woman have nothing substantive to discuss with each other besides the running of the household and kids, they must have the most unfulfilling and boring marriage on the planet. I would never live with such a husband, and neither would most normal women, IMO. Most women do not enjoy being ignored until their husband wants to discuss the new washing machine or whether or not little Shmuley is ready for Yeshivah.
