Based on my figures as a late joiner I definitely have a problem! 
Actually, I have also spent less time on other fora as a result, Primarily for the positive nature of this place and also the focus on things that interest me.
My job involves a lot of problem solving and resolution, often when I’m not the subject matter expert so I have a natural tendency to deep dive into new learning and I can assimilate information pretty quickly. A trait that carries over into my personal life and interests. So if someone asks a question that interests me, I can’t really rest until I know the answer myself!
