Third Party Store Fronts

What’s everyone’s thoughts on third party store fronts like bestapps.com or bestiapps.com? Do they have a place? Are they even necessary?

I only support SlideMe. It still has a new section.

Same here - SlideME is the only third-party place I’ve submitted my apps to.

I also upload to AndroidPit because it’s very easy to do so (they screenshots etc. from Play Store).
