Lee Lefever makes a case for using wikis (definition) as a permanent record for the information sharing that takes place in a blog or a message board.
Anyone who has tried to sift through a year’s worth of entries on a chronological web site understand what Lefever is getting at. He says:
"Blogs and message boards both suffer from the same problem- they are
great for presenting emerging information, but poor at organizing it
for future reference. The “good stuff†that people often need and
companies often want to capture quickly gets buried among all the
comments and messages."
He reasons that if you make it easy to capture pertinent information as it’s being shared, you can build a valuable repository that makes it easier to access the timeless items among all the postings that lose their value over time.
