Personally, "even if I have something to say, why bother writing? It's the internet, and people will either ignore, lambast, misconstrue, say ackshually, etc."
The older one gets, the wiser they become, and the closer they get to realizing that 95% of the things they write online are actually just a giant waste of one's precious, limited time.
(This comment is not going to be an exception to that.)
