Here is a wonderful video by Ward Cunningham about Technical Debt.
(Thanks to my friend James Collins for finding it on his iPad.)
You may want to ‘Wikipedia’ Ward Cunningham, if you don’t know him well.
There is some irony here, since Cunningham invented the wiki concept (a.k.a. wikiwikiweb) and implemented it first, and his c2.com wiki is still considered, by those in the know as the ‘mother of all wikis.’ It was the first wiki. Wikipedia is now perhaps the best-known wiki, of course. There are many other things worth knowing regarding Ward Cunningham.
