Why even bother with social media? I get 500px for the possibility of constructive criticism. But as to 'likes'. Nah. Who cares if something you're done for yourself is popular? IMO a waste of time and emotion. But that's how I feel about social media in general. Bunch of lemmings who'd jump off a cliff if they thought a photo of the trip down would 'go viral' - nevermind the splat at the bottom.
Do it for yourself. One major reason I've resisted any photography in which there's a paying customer.
Just my $0.02.
