I still haven't figured this out. As of today, they have some really nice knols featured on the top of their home page. Take a look for example at Introduction to Genealogy. This is a great knol that has useful information and is formated really nicely. It is easy to see why it would be featured on the homepage. The question is how are they desciding what makes it on to the homepage. Is it just some editor at Google picking out a few nice ones or is it by popularity?The 'Plain old bag o' Knols at the bottom of the page stands in sharp contrast to the nice Knols that they have featured on the top of the page. It seems that they just have all of the same medical stuff that they started Knol out with last week. I have no idea what criteria they are using to pick these.
I can't wait to find out how all of this works. Ultimately it is features like these that are going to decide if this whole knol thing takes off or not.
