&gt; First off Acceptance Rates&#x27; imply an employee relationship.<p>Ah, I can see that.  On one hand though, Uber needs to avoid the &quot;ghost driver&quot; situation where riders open the app and see cars that they cannot actually &quot;hail&quot; so-to-speak.  I could see how this would create a negative market experience for riders...but perhaps acceptance rates aren&#x27;t the best&#x2F;most unbiased metric for quantifying this?<p>&gt; Star ratings are again a black mark.<p>I don&#x27;t know about this.  Driver quality&#x2F;rider experience are part of creating a marketplace attractive to potential riders.  If drivers are giving riders bad experiences, their return to the market becomes circumspect.  Quality control also isn&#x27;t a new thing for market places, to further your Amazon parallel: <a href="https:&#x2F;&#x2F;sellercentral.amazon.com&#x2F;forums&#x2F;thread.jspa?threadID=1010" rel="nofollow">https:&#x2F;&#x2F;sellercentral.amazon.com&#x2F;forums&#x2F;thread.jspa?threadID...</a><p>&gt; If Uber let other company&#x27;s onto their platform and users could pick one of several &#x27;Joe&#x27;s Cabs&#x27; which all share star ratings that would be a marketplace.<p>Now that is an interesting concept!  Allowing drivers to band together and present themselves as a collective would be an interesting Quality Control mechanism.  But I don&#x27;t know if this is malicious on Uber&#x27;s part so much as the market vision they have is limited (e.g. individual drivers to fares).  This might be because of the historical origin of Uber which was targeted towards facilitating &quot;jobs&quot; for private drivers.<p>I think you have some really good points, but I, personally, am still not sure I 100% agree when you say Uber is not creating a marketplace...somewhat because I see a lot of parallels to Amazon&#x27;s marketplace where you see a lot of differences :)<p>I don&#x27;t really want to defend Uber, I have a moral distaste for Walmart type wage avoidance...I just am not sure if I consider Uber NOT a marketplace.  I also have a very incomplete picture so I will keep an eye out for more details about this particular line of reasoning.<p>Thanks for the clarification!
