I discovered it because we use it at work for research purposes.

The other day, I decided to try it on my own website, just for kicks. Man! The list of technology it returned in the Technology Profile was pretty incredible. Then the Detailed Technology Profile where it shows past technology whose footprint still exists on my site as well as giving implementation and deprecation dates? Dang, I was hooked. Look how much has been added and removed of late.

Have you used it? Give it a shot. You can run a couple free tests without paying and without even signing up for a trial account.

I had no idea Typepad uses Cloudflare for hosting. The things you learn.
