Should All Learning Professionals Be Blogging?

On the Learning Circuits Blog, Tony Karrer asks the question, "should all learning professionals be blogging?". If I have to answer this question, I would say no. It´s true that blogs are one of the major tools of the Web 2.0 movement, and blogs are becoming more and more popular. But, Web 2.0 is more than tools and technolgies. Web 2.0 is user centric i.e. the focus has to be put on the end user. We cannot force anyone to use a tool that we think would best fit to his/her needs. What we can do is just to provide a myriad of services/tools, maybe give some recommendations where to find potential resources, services, communities, experts/knowers that might help solving a specific problem or point to what others have done while facing similar problems, then hand over control to the end user/learner/knowledge worker to choose from and use the offered services etc. the way s/he deems fit. This is real personalization!
Since learning and knowledge are social, the best services should foster knowledge sharing and community building and blogs are only one example of such services...
