I think Userfly is a service that cannot be ignored. It’s a new way of getting data on your visitors’ browsing patterns — data that isn’t biased or subjective; data which shows the real thing — the real actions of your users.

Userfly could certainly evolve into a must-use service for web developers.

Wer wollte nicht einmal Mauschen spielen und sich wie im Film Being John Malkovich in die Kopfe der Besucher seiner Website begeben und deren Erfahrung einmal durch ihre eigenen Augen sehen? Mit userfly kann man genau das machen.
