Awesome! I love CT logs and use a service called Cert Spotter [0] to notify me every time a new cert is generated for one of my domains. This knocks out their Q1 goal [1], I'm very excited about their Q2 goal of Multi-Perspective Validation [2]. It will make getting a cert issued to a malicious actor via BGP hijacking much more difficult. I'm also excited about them getting a ECDSA root certificate and was bummed out when it de-prioritized from being a 2018 feature, but Multi-Perspective Validation is certainly a better priority. All this provided for free, lets encrypt is certainly one of my favorite non-profits [3].
