I agree, plagiarism isnt the best way to get your point across, so if John K has been doing this on more than one occassion, then I suppose calling him out in public is not entirely uncalled for.
However, I checked his recent posts and havent seen evidence of this, so I thought calling him out on the basis of posting what appeared to me as something that he didnt write was a little of a "macho" thing. It's cool when plagiarism is called out on account of being a damaging to the subject at hand, but in this case, I just thought John K was called out because he was being a noob by trying not to be one, hence the plagiarism.
I'll be the first to agree, posting your own thoughts is one way to gain respect, but maliciously calling someone out (F1nut's reply) isnt exactly the best way to go about it I think. A PM might be better.
But, again, if John K has been doing this and I have not been a witness to it, then the call out was appropriate in my opinion.
I just wanted to stick up for the little guy. This place need not a jack ass remark for everytime someone does something a little "off".
Just me... I could be wrong. But again, you're right, plagiarism isnt exactly the best way to get around.
