Attention Cloud Warriors!
tl;dr You must go RIGHT NOW and checkout ifttt.com
Why are you still here? what is it? well that page does an awfully good job, so let me ask you a few questions.
Would you like to collect any photo that you are tagged in onto your dropbox folder?
Would you like to automatically add your instagram pictures to flickr?
Would you like to be able to star something in google reader to have it show up in your instapaper?
Would you like to be able to text to your evernote notebook?
well maybe not all (or any) of those, but consider the power at your hands when you can combine things like Dropbox, Facebook, twitter, tumblr, date/time, the weather, email, sms... in an easy to use and easy to follow manner. no one will get this far cause it's just too cool a tool
