Mindless 'likes' or constructive critique

Dan Ginn over at The Phoblographer is rightly concerned that the way social media is structured might be making us too sensitive to criticism of our creative work. It's a valid point, and I applaud his resolve to counter this trend in his own interactions. I'm aware, however, that doing so requires a far greater investment of time than just clicking a 'like' button on someone's social media post.

Going forward I’m going to give detailed feedback for the work that is shared in my online circles. I want to move away from this basic approach of patting photographers on the back.

I have tried this approach myself (although I admit the feedback I've provided could hardly be described as 'detailed'). And although in my case (particularly on my Instagram page) I found it did indeed elevate the quality of my interactions with people, it also took up a lot of time.
