When Google introduced Knol this last week, I was perplexed. I could not figure out why Google would want to compete in this way with Wikipedia or Citizendium. I wasn't going to even post on this, but something I saw in this Chronicle's Wired campus blog post "Can Google's New Open Encyclopedia Best Wikipedia?" caught my eye and I began to think Google's Knol could have a chance. The key factor in Google's favor is that Knol authors stand to make money for their efforts. But I still do not think this Google project will succeed.
Now I love most all things Google, but I would personally rather see Google focus on more innovative endeavors of its own rather than looking at ways it can add revenue by tweaking successful Web 2.0 products like Wikipedia and calling it their own.
