I am a mobile iPhone on the go person but I am intrigued by the questions and answers here. When I come upon a question that I have a strong opinion on I will find the source material I recall reading online and copy the pertinent info found there paste it into the answer and offer a few personal comments. I always include a link to source and give full credit to the source author.
From an iPhone it is not practical to type in my own words the content that I base my opinion on. Should I just not post answers because a brief personal answer gets berated as unsourced opinion and a copy paste with credit to source gets berated as low quality answer because it is not my own words? Dichotomy!
