If you have video, upload it to YouTube whose motto is "Broadcast Yourself" and where the world is already watching, or maybe iFilm (a similar site). If you thought the photo sharing sites were popular, these video sharing sites have taken the world by storm already! (YouTube users can also choose to share only with family & friends by keeping them private, just as with the photo sharing sites.)
Plus, not all YouTube or iFilm videos are submitted by amateurs. Find videos submitted by your favorite media celebs (including music video by top bands) in amongst the videos uploaded by the masses, plus movie trailers and plugs for upcoming shows on cable TV!
Soldiers in Iraq have uploaded more video than war news correspondents have brought back to their networks. You want to see raw, unedited footage - hours and hours of it? War news correspondents are now embedded with the U.S. armed forces but some areas are just too dangerous for correspondents. Soldiers, on the other hand, obviously have access to these areas.
If you want to just add to the world's general knowledge base, help edit Wikipedia. Wikipedia is the people's encyclopedia, in the truest sense of the word. Everybody's an editor. That is, people add their own material and edit what is already there, just as if they were the page's author. It doesn't matter if you have a PC or a Mac or which browser is used.
Wiki (as a concept) is almost as old as the Web itself. It began in March 1995. Wikipedia now has more entries than Encyclopaedia Britannica and is still growing. On the other hand, Encyclopedia Britannica is only edited by its staff and, as such, is universally respected as authoritative.
Wikipedia hopes to be self-correcting when malicious persons change an entry to add fictitious content either to benefit themselves or harm others. When such false content is found, it is removed by Wikipedia users who keep watch in their areas of interest. That said, it would not be reasonable to take any Wikipedia article as a solid, factual source without cross-checking it with other, more conventional sources (such as, again, Encyclopedia Britannica). But, at the same time, Wikipedia can be right and a helpful resource. (You just have to be careful when evaluating its information, etc.)
The "Power to the People" hippies would have been overjoyed if YouTube or Wikipedia had been available in the 1960's. Yes, the 1960's had underground newspapers but mass access to publishing one's own views is definitely 21st century!
