I hate it too, especially as someone that manages a few web sites as part of my job. I was told there was some committee working on it. Hope that's true! I would be willing to help except I don't do mobile responsive stuff (I mainly right documentation and tutorials for our tech web site) and if the web site is going to be re-done it might as well be mobile responsive.
UScA is in the process of completely re-doing the web site.
The new one will be phenomenal.
They are also working on making the national events web sites better and, I believe, permanent so that a new one doesn't have to be launched for each event every year.
There are many things being worked on that you will see being updated with the organization now that Jim Alloway and the new directors are running UScA.
