I think any SEO with some experience should take the following two surveys:
- Take The 2012 State of Search Marketing Survey
- Please Help: Take + Share the 2012 SEOmoz Industry Survey | SEOmoz
- It helps the industry.
- It may answer you some dilemmas (like clarifying things, like finding out new things – see the SEOmoz survey).
- You may feel better for helping the world.
- Your input is very much welcomed.
