Well, in my humble opinion, I can't tell if someone skipped answering a question because of a 3rd Party Best Answer Selection. How can you tell? I personally believe it does stop many from answering the question. I believe many folks see it as a Stop Sign and not a Yield Sign as some are likening it to. As others have said, I too have added to questions that had a Best Answer selected. But only because the question was one that really piqued my interest and the Best Answer really wasn't. However, most of the time when I see a Best Answer on a question I will drift by it as why waste my time if it has been answered. I believe the majority of G2G users are of the same mind. Having a Best Answer selected does not physically keep folks from adding, but I do feel it keeps many folks from making additions.
I am not presumptuous enough to decide if the person who posted the question is not qualified to make a Best Answer selection. A question without such a selection does not bring the G2G Forum crashing down nor does a question that is not closed. I posted the question and it should be my prerogative to select a Best Answer according to my needs and wants, not what someone else thinks they are.
If I went to a Profile that I was not the manager of and added unsourced and possibly erroneous data to it, the Profile manger would then have to take their time to clean it up and could or should contact me about doing that.. Under the guidelines of open site collaboration, I am permitted to make those changes if I feel they are right in my mind, even if they are not. Just because you have the ability to do something does not give you explicit rights to do something. On WT we do not own our Profiles, they are open for interpretation. But a question on G2G is owned by the poster of the question and while it's interpretation is open for discussion on the Forum, it can't be made for the question. I feel 3rd Party Best Answer selection is akin to thread hijacking.
And Robin, I am in total agreement with you about points. Except for a little pat on the back, what purpose does a Best Answer serve. If you want to reward someone for taking the time to reply to a post I feel there should be a Good Answer selection and it can be applied to multiple replies to a post not just one Golden Ticket. I have posted questions where I have gotten a few good replies and was wont to make a Best Answer selection so as not to make the one not selected feel left out.
I apologize if I ruffled any feathers, but this is my humble opinion and like ears, everyone has two.
