I tend to disagree with this statement.

Absolutely a nod of a head or a smile can mean the world!!!

This particular statement is in reference to understanding that liking a photo is more than a button but it can be an acknowledgement of another. Think of it as a digital nod!

Thanks for the feedback for sure — love the thought of a nod or a smile and how it impacts someones day. For sure something to think about more!
