Stack Overflow Comments

Probably not the best for all -1 Helpful

Comment by paloma
about Stack Overflow and Experts Exchange Jul 2014

This can be great if you are a native English speaker .... any misspelling and you obtain a -100000 or your question locked, the best way to obtain reputation and give + only to some who have English as mother Language. For a more professional service I recommend Experts Exchange.

about Stack Overflow and Quora Dec 2011

Stack Overflow seems to the place to go if you have questions about programming! - For more general Q&A I would recommend Quora.
