RainMaker is a new service that leverages the flexibility of the Social Web, and makes donating to the charity of your choice a notably easier task. You see, through RainMaker donating anything to charity is as simple as sending out a tweet.
That is, when you install the RainMaker application you are giving it access both to your Twitter and PayPal accounts. The two services will become interlinked, and whenever you send out a tweet using the relevant hashtags then a basic amount of money will be deducted from your PayPal account, and directed to the charity in question. Of course, the tweet that you are sending itself is also important in the sense that you can include a comment showing your allegiance to the cause you are supporting.
And you will be able to see what a difference your efforts are making by simply checking out the panels that are provided on the site. These highlight all the current fundraising goals. You will see how far there is to go, and if you have the time (and the money) you can simply send yet another tweet.
