I have never heard of them before, and it seems like more of a corporate web site than a research engine. Now you argued that it may be useful. However when I typed in Perl this is what I get...
* Mathematica form
Perl (male given name in the US)
Information for US births:
rank | beyond 1000th
fraction | less than 1 in 12500 people (0.008%)
number | < 200 people per year
(US data based on 2008 births and other SSA registrations in the US)
Based upon the fact that Perl is considered a mans name rather than a programming language I fail to see the deep need for a shortcut for this web site.
