Google Knol

Ok because it provides you support to share revenue whereas wikipedia doesn't provide it. So knol will be the better option if you have adsense and want to share information with public.

I'll admit that upon launch, I dismissed Google Knol as a Wikipedia ripoff, and proceeded to ignore its presence shortly thereafter (amusingly enough because it NEVER appears in google search results despite conspiracy theories at launch.) Given some recent criticism in the blogosphere (must be a lazy news day if a quick search of your name on a web service and a few snide remarks about what you find is a blogworthy). So, I checked it out a little further today, and I'll conclude that although it's nowhere near this reality yet, if google continues to resource it, I think Knol could be a powerful opinion-centric alternative to Wikipedia's encyclopedic approach, and ultimately the two will complement each other nicely. Here's a quick overview of how I think the two services are different: Wikipedia focused on creating individual and unique pages about everything in a massive heirarchy that are subject to changes by anyone who cares.

Apparently Google has gotten sick of Wikipedia showing up in its search engine for every query.  To add insult to injury, Google does not make any ad revenue from Wikipedia.  To combat this issue, they have announced (but not yet launched) Google Knol, which will let anybody write authoritative articles on any subject, and share ad revenue on those pages.  The good articles will presumably show up high in Google search results. I think this is a pretty good idea, but a couple of years too late.  Squidoo has been doing this for a while.  Blogs let you do this as well.  To me, this sounds like a recipe for an unprecedented spam attack by folks who think that Google hosted pages will get special privileges in the search results.   My personal feeling is that only a tiny percentage of people will want to write in depth, authoritative articles.  It's much more manageable - and fun - to say, rate and review things.  If only there were a site like that.
