The Good Things
Google Knol provides unlimited creativity for the writer because of its open-ended policy. This means that the writer is not confined to a specific area only. Posting recipes, opinionated movie reviews, essays, short stories, poems, song lyrics, and just about any other topic in mind are welcome. One is also given the freedom to write about previously published topics. But if you are planning to contribute some articles, keep in mind to stay away from hard-core pornography, hate speech, and the like.
The best thing about Knol is that it's so easy to use. If you have previously written articles on your hard drive in MS Word or in PDF format, you can just easily upload and publish your file. Contributors can embed a lot of audiovisual materials such as slideshows, photo gallery from Picasa, videos, images, spreadsheets, and forms. Added to its features are several social network tools such as twitter, Facebook, mixx, digg, reddit, StumbleUpon and RSS feeds for easy content sharing.
Add to that, the writer may also earn money through the advertisements that are posted on the page. So the more page impressions and page views, the more money the author is paid.
