Million Dollar Wiki is a pay-per-page wiki concept idealized and launched by Graham Langdon which works exactly like the famous Wikipedia but is different to it in the sense that at Million Dollar Wiki anyone can buy a keyword page for lifetime just for $100 and then he/she alone would be able to edit, manage and add content to that particular page.

Million Dollar Wiki has sold over 1000 wiki pages in a very short period of the time and the site concept is definitely unique and promising.

David was wise enough to buy a Problogger wiki page at the Million Dollar Wiki and has started compiling a List of Probloggers from all around the world. If you think that you have what it takes to be a Problogger then visit his blog at eXtra For Every Publisher and tell him that you want to be a part of the Problogger List.

This can get you a permanent backlink from the Million Dollar Wiki without even paying a cent I was wise enough to take advantage of the opportunity and now I am myself enlisted on the Worldwide Problogger List at Million Dollar Wiki.
