AllFacebook also launched an analysis tool for Facebook Apps. Marketers can compare up to three apps at once, review monthly active usage stats and daily growth rates. A list of "top applications," "top "developers," "fastest-growing applications" and "worst applications" are also available on the above-linked site.
