The Return on Investment of Blogging

What's the return on investment (ROI) of blogging? Blogging for dollars is happening already, whereas this great post by Charlene Li emphasises on many more qualitative benefits and ways of measuring their progress, or slowed down performance :

"My colleague, Chloe Stromberg, and I have been interviewing companies about how they measure ROI and realized that we needed to throw the net wider – this is where you come in! The working idea is to create a framework for measuring the ROI of external blogging efforts for medium- and large-sized companies. Below is an outline of ingredients for the framework. Please help us by fleshing out sources, providing examples, and adding/editing our ROI factors – feel free to add comments to this post or to email us directly (if you’d prefer, we’ll keep specific numbers and examples confidential and use them only as background)."

What's my initial investment? It's time, and time doesn't really mean money, it means opportunities.

My ROI factors :
- visitors' retention
- blog stickiness
- average time spent
- echo-effect
- improved networking, communication with colleagues, friends, and of course, ordes of hypocrites
- successfully reaching, retaining, and informing predefined audiences
- differentiated content channel, barely links posting only
- third-party syndication
- self-preservation and self-awakening
- setting the foundation for my successful identity upload and immortality into cyberspace?
