Here's an interesting question someone e-mailed me today before I blew a fuse over paying for editing (posted with permission):
I should save this question for next Friday, but today I read two blog posts elsewhere about some of your techniques. Neither blogger gave you any links or credit. It also was not the first time I've seen that happen to you. What can you do about this?
Not much. Blog links are a courtesy, not a requirement. So far there has been no outright copyright infringement of my posts that I know of (and I did check out the links you sent, kind reader) but if someone were genuinely trying to pass off my work as their own, I'd probably hear about that, too. I'm not what you'd call generic.
Weblogging is about interconnections and information sharing. It's a good idea to credit any source, but the Blog God doesn't strike you down if you don't. You can't copyright an idea, a couple of words, or even a writing technique (and as to the latter, many are just common practice among pro writers.) Also, I think a lot of bloggers simply forget to post the links or aren't aware that it's a courtesy.
Even if they like or use what they read here, some bloggers don't want to link to PBW because of the taint of association and implied endorsement. That sort of thing still holds water in a few parts of the industry, and even more so among blog cliques. You have to do what you think is right for your career, and to get along with your friends, so I understand this and hold no grudges (and if anyone ever wants me to take down a link to their weblog for any reason, just let me know via e-mail and I'll delete it, no questions asked.)
Blogs like mine are easy to raid. I'm not much of a trend-follower, meme-doer or quiz-taker, so I end up writing a lot of my own stuff here. Despite my best efforts to drive you off, you all keep coming back here to read the blog and have interesting discussions. Maybe I should talk about the puppy more often . . .
Seriously, I don't notice that many blog raiders out there, so I don't think it's a huge problem. I think eventually, like James Frey embellishing his memoirs, it will come back to bite those who do in the ass. Why should I waste the energy? Besides, I like seeing my ideas and techniques out there in BlogLand, even if I don't get credit for them. It's a backhanded compliment, but the ideas are way more important than my ego.
