How does this stuff make you feel?

Before anyone kills me for how I personally feel. I'm only using this photo as it was the first one I saw and is really just an example to what I mean. 
I personally don't get the whole "can I get this many likes for (insert whatever it is about)" I completely understand and get someone wanting to spread out information or their happiness. But what is likes going to do exactly? Or what really gets me is the ones like "I'll quit smoking or whatever for this many likes" I just personally don't get the point of it. 
How does everyone else feel about it? And if you do know any reason that seems reasonable as to why anyone does the whole "can I get this many likes..etc" please let me know and I'll happily change my thoughts.
