This question might sound ridiculous to majority of people commenting here, but why are you making the site boring instead of trying to improve its performance (putting additional hardware, ditching Arc, whatever)?
From what I can tell, correct me if I am wrong, part of the purpose of this site is to operate as a testing grounds for Arc. The focus is on making the language better. So rather then improving performance by providing better hardware, it becomes a matter of improving the site through code. Either by changing the code running the site, or by improving the language itself. But given that this is more of a side project, the resources needed to improve the site are limited. Given the unusual spike in traffic, rather then using limited resources to fix it, or sacrifice the motivation to improve the code/language, the boring article approach is being used.
Yes, that. And the site is not trying to be the most popular social news site on the planet. It aims to serve a specific niche that doesn't yet require more processing power.
