Meh joke considering this was paid on public money.
Same as choosing to spend xxx,xxx USD to have .cern when using subdomains would have worked too (and caused less validation / compatibility issues).
As a tax payer in one of the member states, I approve of this joke.
The Web is a side project of CERN, they should have gotten a comped top-level domain by rights.
This page cost taxpayers like 100 Euros maybe. How much money do you think scientists actually make? How much money and effort do you think it takes to post a blog article with a couple paragraphs of text and an image?
They got the intern to write a funny post. Probably took them an hour and it drums up a bit of good press for the Hi-Lumi LHC.
Money well spent if you ask me.
