I've been struggling with how best to send articles I like to bufferapp so that they can be slowly added to various social media in a more controlled manner. Since Instapaper doesn't natively support buffer (although they are planning to) IFTTT seemed like the only way. But, IFTTT only seems to be able to post to one buffer account at a time. The way around this is to use Buffer's secret email address which will post to all of one's default accounts. I've made the recipe available.

This is a combination of two ifttt recipes.
