If you're following a lot of people, there's a really good way
to see if you are targeting your actions well enough; see if you
can actually enjoy your feed. If following completely ruins the
Instagram experience for you by filling your feed up with junk you
don't want to see, you're probably doing something wrong.
Be very, very selective about who you follow. Make it as tight of a network as you possibly can, and as directly targeted as you can.
