You Can Now Turn On Your Lights By Tweeting

IFTTT (short for "if this then that") has been a power user secret for a while. It's a simple way to automate web tasks — like sending all your Instagram pictures to a Dropbox account, or texting you whenever someone posts a Stratocaster for sale on Craigslist. As of today, they're also working with Belkin's Wemo devices, which means that anything you plug in can be turned on via email, SMS and Twitter, or timed to flick on whenever the sun sets. Use these new powers only for good.
