Donate to Wikipedia
I can't imagine an internet without Wikiedpia. Its just everything you wanted to know and more is one simple search away. You can hit random article and you'll be taken to an article about some random historical figure, invention or country you would've never heard of and be given a detailed out line of what or where it is and its cultural and/or historical significance and anything else you didn't need to know.
Its a well of knowledge. Yet people look down upon wikipedia because its free to edit and anyone can edit it. WELL F#&* YOU! It's like a public encyclopedia written by everything and moderated by everyone. Its a modern marvel and should be supported. It has simplifed the way people acquire information and donating to such a thing just seem right to me.
Hell I'm going to donate to Wikipedia... So why don't you?
