If you have recently started writing online and you are gaining traction, it's probably better if you don't read the comments. Don't look at the reviews. Do not interact with your readers. In fact, Even the most loyal reader finds it hard to remember that you are just a normal person.
I see a lot of people going nuts over the last 0.5 stars they have received, especially on RR. It's similar on Amazon where you have frustrated readers shitting on great works because Even the most loyal reader finds it hard to remember that you are just a normal person.
What I do not do is engage in lengthy conversations. I have had terrible experiences, a couple close to stalking. I have met fans in real life multiple times while writing my Italian novels and it’s mostly been pleasant. However, since Even the most loyal reader finds it hard to remember that you are just a normal person, I prefer remaining detached from my audience unless I really connect with the person.
