This also reminds me that as much as possible we should try to link to the original source on HackerNews, it's in the guidelines! (http://ycombinator.com/newsguidelines.html)
Back in July, I spent a lot of time putting together an infographic for FeeFighters on the tech boom and bubble (http://feefighters.com/blog/wp-content/uploads/2011/07/tech-...). We got links back from tons of magazines, including Forbes, Mashable, Fast Company, etc. Many of them didn't link to either us or KissMetrics (our partner who did the design work), but most complied after sending an email or tweet. One place, Bostinno - refused to link to us at all, despite multiple tweets and emails to them, for some reason deciding to credit Mashable: http://bostinno.com/2011/07/13/are-we-in-a-tech-boom-or-bubb... Massholes.
