I maintain something like this personally, in the form of private structured notes, and I know other engineers that do as well. Except we go beyond listing all possible things that can fit into a given category, into instead making quality and suitability judgments about them. What's "best" or the no-brainer/default for a given role, either in the general case or in various special cases. It's a very useful professional technique.
To wit, I generated the following page from my structured notes, and added it to my public website, a few weeks ago:
I like that page, thank you for setting it up. Now I wonder what the 'rest of us' are using, it would be great to see this same list with a larger number of people and what their reasons for picking one technology over another in the same segment are.
That could probably ignite the flamewar thread of the century.
