Yes 3rd level domains receive type in traffic The extra dot doesn't heart the surfer as i saw the last few years (not as com of course but fair traffic)
Third level names only receive typein if an experienced Internet user decides to not use WHOIS and see if a name is being used as a domain hack. Worthless...good luck trying to sell this.
