Type-in traffic is very minimal these days. Owning good classical type-in domains one can tell - the percentage of typed-in visitors is constantly falling in recent years. Not having namely.com we estimate deprives our platform from some 20-40 direct visitors daily, then most of them find us in two seconds via Google anyway.
The look and the sound of a jing.ly address is what very important to us.
For the sake of argument let us analyse traffic stats of four well-developed .ly projects. All of them forward their *ly.com's to shorter versions of *.ly names (bitly.com->bit.ly, chumly.com->chum.ly, graphicly.com->graphic.ly, pagely.com->page.ly).
As you see, .com has zero traffic these days. Well, not true. Of course if we take a reverse sample, when *.ly is forwarded to *ly.com (as in the case of weeb.ly), the lead domain name will have all the traffic. It is all about the marketing in the end of the day.
