Link, Don't Quote

Any use of another person's content, even if done with respect, is generally done with permission only. Some judgment is required. If you are writing a long entry whose multiple points key off another blogger's entry, lots of quoting might be called for accompanied by a link. When a long quote makes up most of an entry, whose only point is to quote someone else's entry, you are basically stealing that person's traffic. That might seem like a harsh judgment, but a more appropriate entry would offer a small quote and a link, so readers can get the goods at the source, not from your blog.
