As we all now, IBM counts thousands bloggers. What people often ignore is that IBM also have internal blogs that preceded the public blogs.
In this interview, Christopher Barger, IBM’s “chief blogging officer” tels something quite interesting about internal blog’s effect on intranet frequentation:
“we launched the blogging initiative internally, and that story on our intranet experienced six times the normal readership”
As it’s a well known fact that intranet managers meet lots of difficulties making people use corporate intranets, it may be an interesting clue for them.
This brings another question : can we consider that blog based intranets increases the ROI of all the others applications that are on the intranet ?
