Citing My Sources

As a middle-school English teacher, I always taught my students to cite their sources, give proper attribution, and never give the impression that someone else's idea is your own.
A new wrinkle in this is giving credit to someone in the blogsphere for a tweet on Twitter or a post or comment on a blog.
When I send out a tweet or write up a post, I try to link to the original source. But with the avalanche of information coming at me, I find it nearly impossible to track. Plus, current thinking is that with many people now using Creative Commons licensing, writing and photos will be used all over the web, mashed, stretched, re-worked, and re-vamped. I know I've found many photos with no attribution (and I've done it, too, when I forget to go back to copy and paste). If you take the photo from that post, do you give the secondary user credit?
Complicated.
Early this morning, I first saw the story about the student jailed in Egypt using Twitter to reach out for help on a post by Michael Arrington on Tech Crunch, or was it Chris Brogan's site? I'm not even sure anymore since it also popped up at least 10 times on different Twitter accounts as first-time tweets and many other blogs during the day. If I decided to write about it later, I would have had a difficult time trying to remember where I first saw the reference. (And I know and remember the old, "if it's mentioned in five or more sources, you don't need to cite it...but go with me here.)
Many times I see tweets and posts about reviews for videos or applications I've already tried. So if I choose to write about them later, whom do I credit? Or do I, if I've stumbled upon them myself but have also read someone else's review? What about referencing comments on a blog? What if the comments have moved to another blog? I'm not talking link love, here. I'm talking old-fashioned, getting the attribution right.
The conversations about how to sustain archives of digital information are also fascinating, given that information may not always be with us in the existing format.
"How do we archive information when the technology to read it, and indeed the information itself, changes so fast?" asks Josh Catone on The Read Write Web.
The past few days, I've read several posts about giving credit where credit is due. Some folks want to be recognized for breaking the story first, even though it's darn near impossible for anyone to know who said what first. And what about RSS feed sharing? Who owns the information? Does it matter anymore.
Frankly, the only reason I care is that we've been teaching our students the importance of proper attribution forever. When I work with students and teachers, I want to be thoughtful in supporting their research and citing of sources in however they decide to present, publish, write, or digitize. Shouldn't we all be saying the same thing?
Ah, life was easier when I could pick up a book, grab the information, and follow MLA style.
Even Robert Scoble weighed in on this, saying:
"The era when bloggers could control where the discussion of their stuff took place is totally over.This is a trend that the best bloggers should embrace. Me? I follow wherever the conversation takes me.
As someone else wrote: steal my content please."
If anyone is developing new guidelines for their students, I would love to know. How do you cite Twitter, for example? I couldn't find anything on MLA when I looked. Carolyn? Anyone? Do we even bother to cite it?
For all I know, someone has already written this post. I just can't find it.
Just thinking, here....
