lanabyte: TV and computer are in separate rooms, but I do usually keep either the radio or youtube playing.
Here in the forums it's maybe acceptable, coz you do not expect an immidiate response. But I had a few ladies online chatting and I was waiting for a response. When I finally got some attention, I was told "... Sorry, but I was watching TV"
I think this is very impolite, same as you would talk to somebody who is constantly staring on his TV screen!
