Do Not "Like"

I am amazed at how lazy I am becoming in regards to commenting on people's blogs (when I even take the time to read them).  I want them to know I have read them and appreciate their post (as I want people to do to mine also), but I'm often not sure what to say - "very insightful"?  "great post"?  "I totally agree"?  These seem generic, pointless, and unnecessary when I can usually just click "like" on Facebook. I can't believe that I've become so lazy though.

I know the general trend in electronic communication is to keep it short and sweet, due to the prevalence of Facebook and texting, and as an engineer I approve of the efficiency and effectiveness.  But I really hate to see the unfortunate (although expected and understandable) side affect of modern communication methods become the degradation of extensive and thoughtful expression, especially in myself.
