Earlier this year twitterers in more than 200 cities held face-to-face, offline festivals to raise money for charity: water, a non-profit dedicated to providing clean water to underdeveloped nations. The fundraiser generated $250K, which the charity used last week to drill wells in Ethiopia. Watch daily video updates of the project.
On a related (though admittedly frivolous) note, our friends and favorite rouge tinkerers over at MAKE devised a way to use Twitter to have your plants remind you when they need water. The plants even send a sweet note of thanks once you’ve soaked them. Although more of a novelty than a revolution, these high-tech tweets can help avoid wasted water—and dead plants.
