> If the data isn't protected by copyright or trademark, (e.g. public data, such as an address of a house), it's free to reuse. At the risk of stating the obvious, most data you'll find is protected by copyright. Eg this comment is written by me so according to nearly all jurisdictions in the world, I own the copyright (unless HN has a clause that I agreed to when I signed up that I sign it away, like stack overflow has). Most forums, blogs, essays, articles, news sites, recipes and song lyrics are covered by copyright. I'm pretty sure that a webshop's blarb about why product x is good is covered by copyright.
