Since you had to make a throwaway for that comment, I'm not convinced it's a concern you really had nor that you work at a place that can't even give you the modest amount of doubt-benefit to click the URL before calling you into the office for a chat.
This is called the ol concern trolling.
If your workplace uses Ruby, people there should probably be familiar with Aaron Patterson (AKA tenderlove). He's been a prominent Rubyist since Rubyists had any prominence.
'tenderlove' is a core Ruby (and Rails) team member, BTW :)
If your workplace can't handle a 1950s euphemism for vanilla sex, that URL is the least of your problems...
Your browser prefetch probably already did the DNS lookup anyway.
While I understand the hesitation, the post is certainly SFW.
