From Sébastien Paquet and Lilia Efimova ... some interesting insights as to why people blog and why some professions are better represented than others e.g. educators, journalists, software developers, librarians, lawyers and knowledge professionals. As Sébastien says in his original posting
on the subject :
I think the commonality has to do with uncovering the implicit.
And as Lilia adds
For me, blog is something for articulating ideas. They get some shape once they get out of my brain, and it becomes easier easy to deal with them. Blog is something for catching those difficult to catch things...
I think they are on to something here - some people because of their mindset "can't help but blog" while others will "never get it" or never find the time or the motivation to do it. And that's not a judgement - it simply reflects the diversity of human nature and that can only be good
