Occasionally men ask me if they are 'reply guys' or how they can avoid being a 'reply guy' in a woman's mentions. My answer is always to consider these two things:

1. does the thing you're saying really need to be said, or are you simply trying to find an excuse to talk to the nice internet lady?
2. would the world be a better place if you just shared her post instead?

If one wishes to avoid interaction one perhaps might avoid systems literally conceived and engineered to promote interaction. Such a person might choose instead their own comments-not-enabled-blog for sharing their thoughts without risk of unwanted comments. ymmv
