Addiction to steemit is 100% good. Everyone is addicted to something. Now the question is "how productive is it"? Some of us are addicted to facebok, whatsapp and other social media networks that gives us virtually nothing except "Likes" which can't put food on your table. But steemit gives you cash.
Since i entered steemit, i hardly visit my facebook anymore and am sure its same with most of you guys. I wake up, instead of checking how many likes i have, i check how much money my post has made on steemit. If my addiction gives me money, then its good for me, no doubt.
