I grew up in the Greek Orthodox Archdiocese of N & S America ("New Calendrist Greek Churches" as it was called above) and never knew that confession was an Orthodox practice until I was in university, where there was a local OCA presence where confession was practiced. I had definitely read about it, but just figured that the Orthodox Church had dropped it somewhere along the way.
Why was my home church this way? To this day, I still don't know, but I think it has something to do with the Greek Orthodox wanting to distance themselves from the Roman Catholics (who were the practicers of confession) and wanting to gain favor with (or to be more like) the overwhelming Protestant majority in the Northeast USA where I grew up. I have heard that things are changing in the Greek Archdiocese, and even see articles these days urging the people to confession in the "Orthodox Observer." I think I was short-changed of spiritual benefit because confession wasn't encouraged. It's the best spiritual medicine (along with Holy Communion). To this day, I have Greek Orthodox relatives who have never been to confession, and I do feel sorry for them.
I encountered "general confession" only once -- I was visiting a church for vespers, and there was general confession after vespers. I thought it was very "hokey" also (great word!!) -- sort of like the chicken's way out! Thankfully, I've never been to "general confession" again, and my subsequent parishes haven't offered it.
That is so true what Fr. Seraphim wrote above -- we need to be trusting of others, especially in these current times, when it's encouraged to NEVER trust others. My priest doesn't require confession before each reception of Holy Communion, but a good rule of thumb I heard was from my priest while living in Arizona and worshipping at an Antiochian church there (in Tucson): 4 times a year at least. I don't even know my priest that well, but I feel good confessing my sins to him -- I don't feel that he's judgmental at all.
