Yobi3D is new 3d model search engine

Yobi3D is new 3d model search engine. It searches for 3d models on other repository sites based on input keyword.
I took a look at those models and many of them are not optimized for 3d printing.
I noticed that many other sites call each new 3d model search engine a "new Google" for 3d models. Qhat will happen if Google has 3d model search function? Will all those sites go out of work?
Still, I welcome any new site.
