There is something “clunky” about the website, but to be fair, the first page has a big button to download the installer, which leads to a page where the first link is the version most people want, the second link leads to instructions how to get it onto a usb (or cd/dvd) for linux/windows/mac, and clearly visible a link to all the other versions of the installer that people might want, with explanations what they are for.
For me it’s hard to put my finger on why the website is bad, all the information is there. I do agree that it just somehow feels bad, but I don’t understand why.
