Having used Wikipedia on occasion in the past, my reaction has ranged across the entire spectrum, from either impressed at how well the Wikipedia entries have been written, researched and presented, or dismayed at the lack of anything.
I was recently listening to a story on NPR's All Things Considered, where the articles in Wikipedia were assessed, and even compared to Encyclopædia Britannica for content- and the finding was that Wikipedia was in fact quite comparable in terms of technical content and accuracy.
After a little consideration, of course it sinks in that this is indeed a flourishing collaborative project, the success of which depends on active participation and contribution. So, I've started to put in my humble $0.02, wherever possible.
Helping out in the community- at least until the next, brighter and more knowledgeable guy comes along, and I'd encourage everyone else to do the same in their fields of knowledge. Wikipedia looks like it's becoming a genuinely useful resource.
Anyways, here's what I'm up to on Wikipedia: http://en.wikipedia.org/wiki/Special:Contributions/David_G._Smith
