Or just use google.

Google is a great tool, however not all users are proficient at using the advanced seach options. Normally the results of vague searches further confuses the users, and in the case of a potential switch to a Linux based Distro the user can become frustrated with Google and consequently with Linux based Systems because of the difficulty they have finding information.

I welcome this dicussion to continue and if the need arrises then we can help others to learn to use google more effectively.
