Smart Linking and Wikipedia

Wikipedia is great for all research work. One thing I really like about it is the easy with which millions of links have been placed under it. The links are in totally understandable form. Many times I just type what I am looking for in the link itself and nine out of ten times I am taken to the correct page. It really amazes me that if such a gigantic site is able to keep their links so simple and clear, of course having an awesome engine like MediaWiki helps but I fail to understand why other small scaled sites aren't able to do so. So learn from wikipedia, if they can keep their links simple so can you.
