Wikipedia is an open source encyclopedia project. Do you know anything about anything? Of course you do, so why not contribute? It’s harmless geek fun that produces something truly useful. In these days when copyright and patent laws keep fencing off our common culture, it’s nice to see people creating knowledge that can’t be owned in any traditional sense (if that smacks of communism to you, move on; nothing to see here). One easy way to contribute is to surf the most wanted pages. These are pages that have already been referenced by other articles but that don’t yet exist (is that strange or what?). Wikipedia parses articles for key words that don’t already have entries associated with them. So, if you hit the most wanted and see something you know about, you can fix problems in real time. If only the rest of life were so simple.
