ifttt
ifttt—short for ‘if this then that’—lets you write simple rules that convert activity on one web service into action on another.
So, for example, you might say to ifttt, ‘If I save a bookmark on Pinboard tagged ‘tweet’ then post the link to Twitter’. Or you might want ifttt to post to Tumblr when shares in Google drop below a certain price, or have ifttt call your ‘phone whenever it starts raining in your home town. For more ideas, see the ifttt recipes page.
In other words, it’s a Hazel for the stuff you do online, or a non-bewildering Yahoo! Pipes.
