Contentious blogs about why she blogs...

and here goes another one about why someone blogs: Blogging as Exploration:
CONTENTIOUS allows me to think things through, and to connect and learn, in public. It helps me evolve my perspective. As a byproduct I believe it helps establish my credibility – even though I sometimes say things here I later change my mind about or regret. But for me, the most compelling benefit is that it allows me to open my mind and share with people who have related interests and diverse perspectives.
