Old but gold
What Seth Godin says in his post may be applicable from the very first day of social media advent. Something you should better remember anytime you start your hunt for likes:
More than ever, people, lots of people, hordes of anonymous people, can watch what you do.
They can see your photos, like your posts, friend your digital avatar.
An essentially infinite collection of strangers are in the audience, scoring you, ranking you, deciding whether or not you're succeeding.
If you let them.
The alternative is to focus on the audience you care about, interacting with the person who matters to you. Your audience, your choice. One person, ten people, the people who need you.
Everyone else is merely a bystander
