For all the people (4) who are using AJAX Tag (
http://www.kinlan.co.uk/AjaxExperiments/AjaxTag) and Ajax Tag 2 (
http://www.kinlan.co.uk/AjaxExperiments/AjaxTag), who have noticed that the Wikipedia Articles are not being found it was due to a problem on Yahoo's end. I must commend the people at developer.yahoo.net, Toby Elliot especially for getting this rectified. I must also say, out of all the Online Web 2.0 API's that I have used Yahoo seem to be the most helpful, you report a problem and they are very honest and quick to fix any issues. Way to go guys!
