There’s been a lot of talk about Google’s opening of Knol for contributions. Not everyone is sure what to make of it or if it will be worthwhile.

And then there’s Aaron Wall’s concern with Knol and copyright issues. It’s a problem you will want to consider before publishing a Knol.

I have been seriously considering giving it a try for some of the areas where I’m having trouble ranking anyhow, but have plenty of information to share. If I’m not getting Google traffic for it anyhow, there seems to be some potential for me to benefit from this.

Early results from Search Engine Land show Knol pages are getting excellent rankings very quickly. This may not mean they will stick, but it’s something to think about.

And of course there’s the simple fact that I like having more control than that over my content.
