Jawad has posted a blog entry about how to calculate the Cache Node Size for a MCMS site. Unfortunatelly he used the query from an KB article which has been updated a couple of month ago in his blog.
Beside the fact that copying KB article content to a blog might be a copyright violation this now also caused outdated content to show up on a blog - which might actually confuse other users.
It is always a good idea only to add a reference to the KB article rather than to copy the content. And if partial content is copyied a reference to the KB article for follow up should always be included.
There is another blog entry on Jawads site that is actually a copy of a KB article: http://www.geekswithblogs.net/jawad/archive/2005/05/13/39625.aspx.
Jawad: I also tried to add a comment to your blog entry but it only caused postbacks without actually adding the comment - although I correctly entered the code shown in the image. You might want to check into this.
