If you really like someones blog, drop them a little message telling them.
If you see someone’s selfie and think they’re pretty, tell them.
If you see someone’s having a hard time or a crappy day, inbox them telling them how much you appreciate it.
If someone posts a cool edit, tell them how awesome it is.
Sharing a little love around the fam isn’t hard and doesn’t take much, but it has a lovely affect and there’s no better feeling that making someone smile. :)
