The answer is pretty easily and immediately 'No' for me. So much of my IC time is spent trying to be relevant that I am actually pleasantly surprised whenever I have an interaction that is just fun. I enjoy the moments that I enjoy, but they are fewer and further between than the payoff I get from any other hobby I have, whether it's writing, editing, reading, or redecorating my guinea pig enclosure.
When you add on top of that the fact that people begrudge you the fun you have or accomplishments you achieve, through passive aggressive IC or OOC communication, turning moments of happiness into the chore of carefully spot-checked and proof-read responses to bullshit accusations...
The less time you devote to this hobby, the more the bad stacks up versus the good. I don't have the free time/friend group I once had to MU for enough hours per day to break even, let alone come down on the side of 'yes'.
I love the hobby, don't get me wrong. But it's a bit like cigarette smoking I think, with the disclaimer that I've never been a smoker & am speaking from second-hand experience. I'm so used to doing this that I get antsy if I don't do it for a while, and I recognize that while the short bursts of pleasure are pleasant indeed, it's not great for my health.
