Sorry, I didn't know where to post this but does anyone else feel that backing up one's position by linking to Wikipedia should be banned on PF? In my opinion its too easy to do and the great thing about PF is that industry professionals congregate here to give professional answers that are customized to the questions asked. Linking to Wikipedia is not an answer. Nor is linking to a google search page. We aren't internet infantiles, if we thought we could get the answer we wanted easily by going to Wikipedia or Google, we would not spend time posting questions here. Personally, I find that one of the best attributes of PF is that its an intellectual database where civilians and novices (like me) can ask professionals (like Garth, ZapperZ, Spacetiger, Varnesch and many others...) questions about advanced physics topics. I like to read popscience books like 'A brief history of time', and 'The elegant universe' and then come here to ask the tough questions that these books skim over. As a bonus, the professionals here read tons of white papers and can always refer you to the niche papers that cover EXACTLY what your question sought to answer. I guess I'm just frustrated. Am I wrong in thinking that linking to google and Wikipedia just dumbs down this site?
