Personal Request & Blog Question

Today I met someone who, upon meeting me, said:  "I read your blog!"  This has happened to me a few times.  But I am always surprised (happily, of course) because I have no way of knowing whether or not my posts are being read.  As we talked, she asked me about that, so I thought others might not realize either that, indeed, I have no way of knowing unless you check a box or write a comment.
Sometimes I get discouraged.  I have plenty of inspiration to write but I don't want to write into an abyss...!  So I am asking you for a little feedback.  Or just even the most minimal response.  That's why I put the boxes there, to make it easy.  I'm not about to quit, but, eventually I will if there is no evidence that I have a readership.
The question is about Amazon.  Google is persistently asking if I want to make Amazon available to my readers.  It means that if you learn about something here that could be had from Amazon store, you could buy it right from here.  The remuneration for me would be miniscule.  I would add it only as a convenience for the reader.  But, so far, I have stayed away from commercialization.  I tried Google ads for awhile but I took it off as some ads were inappropriate.  So, what do you think?  Do you want to be able to order things from here?
