If you select PHP, you get "So you like your variable names to include dollar signs? That's cool, everyone misses Perl once in a while." Making smartass remarks about their language of choice is not a great way to initiate a relationship with a developer.
While this is obviously intended to be humorous, I don't really care for the way it attacks the users of the language in such a mocking, patronising manner.
Criticizing languages/paradigms is fine (the resulting flame-wars add a great deal of humour and interest to the world of programming) - but to caricaturize users of different languages as people suffering from certain negative traits is just ugly and leaves me with a bad taste in my mouth reading this.
I for one would not want anything further to do with this author or site.
I was kind of annoyed when I got the first remark after selecting C, but once I found out they made fun of everything, I actually started to like its criticizing.
Notice that selecting any language gives you a dismissive remark, not just PHP. But you're right in that it's probably not the best way to cast a wide net (unless they're intentionally selecting for contributors with a good sense of humor).
Except for Rust which takes you directly to rust-lang.org. I actually like the idea though. No language is perfect and people do seem to be a bit too sensitive of their favourite languages.
