Do the rooskies use the inverted exclamation point? Only place I have seen it is Spanish, and I learned some rooskie in my younger years in preparation for a trip abroad.
No. I just like the practice. Though the only really good improvement on English punctuation would be to use French quotes, «xxx». The idea is that commas and periods would look good either inside or outside quotes; with current English practice, commas and periods go inside, no matter the logic. It's a small matter.)
