Critic time. This site is more enterprise-vanilla. Like many others you have fallen to the trap of using any dom api feature, without stopping for a second and thinking, "Do I really need this? Does it actually make my life/code easier?" The answer is no. 26 lines of code to add a single avatar image with alt text? This should have been a 1 liner.

You don't have to use every feature out there. Getters that return 1 element that will never change. Splitting what should have been 1 style.css into 5 different files. Too many "best practices" for "complex" software.
