#1 rule of Instagram

If you don’t want to ruin Instagram, please follow this simple rule:

DO NOT pick a photo off the internet, your computer, DSLR or whatever device, then transfer it to your smartphone, then apply a filter and post it. Extra douche points awarded for Tumblr pictures which appear on Instagram. Oh and no, applying filters to already modified pictures is also massively Douche bag-ish.

If you follow this simple rule and for crying out loud just take a photo on your smartphone and directly post it to Instagram, you’ve understood the brilliance, simplicity and success of this wonderful app. Remember: Facebook isn’t going to kill Instagram. It’ll be you.
