I think you've found the formula for the best discussion of technical and scientific issues on the web - editor selected stories and reader moderated comments.
Whenever I think of a story to post to slashdot, I try to anticipate how people are going to respond, but when a story is accepted, I am always amazed by the diversity of opinion and the startling insights I see generated. Slashdot is online brainstorming at its best with the benefit of tens of thousands of smart people looking at an idea and providing their unique points of view
I think Vernor Vinge said it best in his dedication to Rainbows End. "To the Internet-based cognitive tools that are changing our lives -- Wikipedia, Google, eBay, and the others of their kind, now and in the future"
To that distinguished group, I would definitely add slashdot.
Best Regards and hopes for 10 more years of slashdot success.
