Panic’s blog respect its own history

The software company Panic has a blog, and has had it since 2009. It has a clean, modern aesthetic that looks something like that:

However, something interesting happens as you start going back in time by clicking Older Posts at the bottom – the historical posts are rendered using their original styling:

This isn’t something that happens for free, as with any redesign every piece of content gets ported to a new framework and style by default. So, I gather this was an intentional thing that also required extra effort both to make it work like this to begin with, and to allow the old style to appear nicely within the different confines and technical realities of the new style (you can compare the above screenshot of Firewatch announcement as retrieved today with its original appearance in the late 2015).

I love this effort. I wonder if more places on the web could use that kind of thinking. As an example: what if your social posts or blog posts from long ago came adorned with the same avatar that you used when posting them, even if you updated it many times since?
