I definitely do! Quite a lot of them I watch a bit later (often later on the day, sometimes a day or two later), so I don't really get to posting about it in the threads during the live competitions
Biathlon, cross-country skiing, alpine skiing, ski jumping, bobsleigh, skeleton, luge, ski & snowboard cross, speed skating and short track are the winter sports I definitely follow and watch every main competition of (World Cups, in the case of biathlon also IBU Cups and for speed skating of course also national championships). The freestyle stuff....nah, I just can't be bothered, and I find it beyond annoying that skicross is part of freestyle skiing
