Hi SRGT BUBBLES,
Thanks for pointing out your comment about wikipedia. In fact, your comment is true about any information on the web.
I know I often give a web reference as the answer to a query, as do may of my fellow experts. With any luck, we have determined that the information that we're passing along is factual. There is a safety net: the other people on the board can, and I hope do, point out errors. But, please be skeptical.
The comment you make of multiple sources is good. Remember, however, that one source may just be collecting information from another source, without attribution. So it always pays to be cautious, even if there are multiple sources.
