Often we're stuck in situations where we don't have the necessary domain knowledge about a topic/time just enough to research about the topic/client deadline.In those dire situations it is better to ask from someone who might have done it before/might be an authority on that topic.
Also we being an authority on a topic takes years of hard work practice & time & that certainly cannot be given for free. We at Michael Angelo realized that social networking sites/blogs/Q and A sites gives you a general idea about how to solve the problem
On other hand web search /research are too time consuming & may or may not generally guide us to the solution . That's why we built Michael Angelo for ourselves.
