I'm retired and a Broadway fan. I have a laptop on a rolling stand next to the couch, so I check it throughout the day - it's often left open on a tab on my browser. I also keep up on All That Chat, however I've been spending more time on BWW these days.
I use it to keep abreast of happenings on broadway and also in my hometown, SF. We travel to NY typically once a year, so I use the boards to keep abreast of what's coming in and whether the shows are likely to be something I want to see. I also follow their weekly box office grosses posts. Finally, as a fan, there are so many aspects about acting, stagecraft, and the BUSINESS of the business, that fascinate me.
And sometimes I just want to gush about a show I just saw or an OCR that I've re-fallen in love with.
I post a few times a week. As I mentioned earlier, I used spend more time on All That Chat, so my level here is still a few hundred short of "Broadway Legend" status, not that it matters a whit.
