So long as it's not harmful, and is helpful to sobriety and learning, even perhaps fostering improved communciation skills, I see such benefit in this medium of written exchange.
As for being "addicted" to recovery (I've been accused of being "addicted to writing"), that may be true. But I also regard it as essential to my sanity, and now direction toward recovery. That I've not tripped in four months but had been every month previous for decades I think is testimony to the power of being connected...at least through written word.
As can be said about pretty much everything, examine your motives, and you'll know the answer.
