I think it's time to create a personal blog. For a few years, I've been blogging at New School of Information Security about information security, especially risk estimation, metrics, and risk management. I've used Twitter (@MrMeritology) for these and other topics, including various topics related to my PhD program and dissertation. I'll still blog at NewSchool from time to time, and I will continue to use Twitter for community interaction and resource sharing.
The blog format allows for longer essays and maybe novel content (e.g. interactive animations). I imagine this blog will be more open in terms of topics and ideas that interest me as I come across them. I'll also be blogging my progress through my dissertation and my experiences with various tools and methods as I learn them.
The content will be mostly professional, intellectual, and technical, with some occasional philosophy and personal essays.
I won't be blogging personal or family stuff.
