New to HUGO, but I have been on top of developments and predicting the need for static site generators as a development phase for note organizers like Evernote, and TheBrain, and page-mockers like Corel Draw, for a decade.
I have been through it trying to find the tools to fit my needs as a knowledge-level engineer and hacker-developer. HUGO has a thing - simple, direct, and I am hoping flexible and powerful with regards to keywording and search. I am just arriving, recall.
So, a blog should firstly not be about HUGO - it could literally cover any subject. But it should BE HUGO - a demonstration, a sampling. So, you need two good high concepts - and I would say the second should be about high level KM/KE/IE developments and overview. All you need is an editor to set it up, manage it, get feeds, perfect tricks, and show how its done, and stick to a clear ideal of what the path of development MUST BE.
