How to do good/bad is SharePoint programming?

 Good programmer

• Learned to setup/administration/updating
• Have knowledge developing/debugging 
• SP is good for application with simple data model, preferably read-heavy. A huge strong point is what users/administrators can achieve with configuration only. Change data structure on the fly, modify look and feel, etc. A wonderful platform for "my books" kind of things

Bad Programmer

•  Its only for Documentation
