I have the impression that we are planning too much and doing too little practical work over the blog revamp. We are still discussing ideas whilst no practical, viable, blog infrastructure is coming out of it. I'll first enumerate what I believe as being the issues we are facing:
- Resistance to a wordpress solution, this is given the fact that wordpress has a horrible record of security problems.
- Variety of possible engines to use: jekyll, ghost, or wordpress itself. Possibly others (if it was me to do admin I'd love Django :) )
- Hosting. One thing is to choose an engine, another is to be able to host the resulting blog. Hosting cost money after all. A wordpress.com (the hosting service, not the engine) or a github pages jekyll would be a solution to that but again we are discussing both the engine and hosting at the same time.
My take on figuring both things at the same time is to make a wordpress export from the current blog, place it in some file locker and add to this meta question. Then, anyone of the people willing to help in the creation of the blog, can simply build a prototype. We would be able to make the prototype in whichever way we want: hosting service, github pages, even write a blog app from scratch (although I would not recommend the later).
If we have several prototypes to choose from it will provide with a better discussion than the uncertainty that we have now. Even if some part of a prototype would not be perfect we would still have a blog, and be able to improve it if needed. Note that several prototypes will fail, that's a good thing, since we will be eliminating risk from bad decisions from the start.
