(68,084 posts)followed by the link to the full article, then people will be less likely to assume you wrote it. I also like to use a "blockquote" tag, to set off my own note from the material I am quoting. (Actually, I also use a different font color to set off quoted material, since people often skim too fast and miss the note about its being someone else's writing.)
Putting the link after a long passage, with no note at all, though, pretty much guarantees that many will mistakenly assume you wrote it, leaving you to post endless disclaimers.
ON EDIT: Of course, even with such precautions you won't prevent every person who responds from mistaking the quote for your own writing, but you will significantly reduce the number of times you have to correct the mistake.
