When some take the time, and make the effort to write a post, it would be stupid to not thank him and to try to start a conversation with him.
More than stupid, it would not be very polite nor even friendly.
When I see a lot of our new members involving themselves in writing a post, a review, well, in sharing something, I think all the work we do here is gratified by them, and that makes us very happy.
When my job takes me all my time, I am not here, don't worry, at least I have no time to write, and I shortly come here to see, read, and briefly answer.
But I try to do it every day.
That is not too hard, my friend.
Best,
Nicolas
