In Everyone needs to know what we do here, I wrote:

The fastest way to lose credibility in a technology company is to say that you don’t understand technology. It’s okay to say that you don’t understand a new idea or a new implementation but to be effective in technology marketing and product management requires domain and technology expertise. People who tell you otherwise probably aren't very effective in working with technical products.

I was curious what others thought about the importance of domain knowledge so we asked some of our favorite bloggers to comment:

• Jeff Lash at How To Be A Good Product Manager
• Saeed Khan at On Product Management
  
• Roger Cauvin at Cauvin
• Bikram Gupta at Thoughts on Product Management

You can read my original article with their comments appended.
