Hey check this out guys,
Here is a tool that is completely free that will help you determine which keywords etc, are already being taken by squidoo lenses etc, tell you which lens will be available to you and will help you determine which type of lens to create which will be profitable. I haven't tried it yet, but it certainly does look like it's worth checking out.
I just got the email on it just now. It says there is only 500 available right now, so you might want to grab it while it is still free. Maybe it will help all the squidooers a lot.
