hello thank you very much for the link but in my defense I must emphasize that wikipedia is in its entirety the content is of dubious origin. I would never use any wikipedia or to make a university essay because the information that is uploaded, anyone without certification could adulterate. my content is my own, of analysis. Thanks for the quotation and my sincere apologies! I do not use wikipedia. Currently there is not only the plagiarism in steemit for subjects who have little time or creativity is scarce, I do not know the scope that may have wikipedia, no sè com really works for the users of it, without a doubt it is one of the information networks that offer a lot of support but I prefer the kind of networks where only qualified people publish content with sustenance, with this I expose my total offense because I would not do something so bad and less than a page with the low reputation as it is, the one of the link that you suggest
