Can you tell us what you mean by "this platform"? Are you referring to
Google Answers itself?

the platform = answers.google.com

Hi sabiny-ga,

I must admit that this is the best service out there now.  

I have been a member of most of them and this by far exceeds them. 
For the others you do not have to take a test to be an expert and your
communication is not monitored closely to ensure customer and client
satisfaction like this one.  Your answers are not posted publicly for
all to see your performance and content and there is no set guideline
as to how to answer questions. There are so much more to it. 
Nonetheless here are the competitors, all are .com
