Who would search for jw. in a search engine anyway?
I get similar results in almost any search engine I use. duckduckgo, dogpile, bing, google etc
I get the feeling that putting the dot at the end just tells the search engine to search all the extensions .com, .org, .gov etc and return the most comon one if it finds one.
Yahoo also returned and advertisement for jwmatch.com. I saw a couple cuties that make me want to go back
