The barrier to entry for content creation has been lowered so drastically over the past few years that it seems just about anyone can hop online and create content. As long as you have an email address, you can easily sign up for online accounts that will allow you to share text, pictures, audio, video, whatever. Much of the web is still focused getting people to participate in such a way that generally means we have to embrace the crap with the cool.
As great as participation is, I'm a firm believer in the direct correlation between how easy it is to generate content and how much that content will suck. There's so much noise, clutter, and garbage sucking away bits of our lives that it seems content is adding less and less value (think "make me unsee that!"). And the people who try to game the system when they just don't get it (read: clueless advertisers) certainly don't help when they hop along this internet ride 'cause everyone's doing it.
The less jaded perspective is that all this trash sure makes for a good opportunity. Though what we share may not always be worthwhile to everyone (value is in the eye of the beholder), it seems that standards are lowering quickly enough for us to stand out with some honest effort and dedication. Good luck if that's you and may you never surrender that fight.
