Just got wind of a new private beta, called TapeFailure. It sounds pretty exciting to me, and takes web analytics a step forward. By inserting a small 10k script in your page you can record and playback the actions a user takes on your web page.
I’ll be interesting to see how this pans out, and what affects it has on performance. If it works ok, I can see it becoming a fantastic way to do really discounted, cheap and dirty usability evaluation. Although you clearly won’t have access to the user directly, it should give some great insights on what users are doing in-situ and unaware of the monitoring.
Clearly, there may be some privacy issues, but let’s cross that bridge when we come to it.
