I don't have the data to quantify it, but M-F, 6a-4p, maybe once an hour or so just to check the headlines. If I have comments, I might check my threads to see if I need to respond. On the Weekends, though, I might check it in the morning and again before bed just to see if anything interesting happened.

But it isn't like YT (which is running in the background nearly 24/7) or Reddit, that I habbitually check. Those feel way more addictive. Same with Instagram, but I don't really care for short form content, so it doesn't capture me the same way as news and long form videos.
