Weekend read: My weekly share on Twitter

What happened in your world this week? End of the week, for me, means a look-back to get perspective. I've gotten into the habit of using Twitter as part of my notes for the week, and this weekend read list helps me recall what caught my eye and got shared. I'm @dontgetcaught on Twitter, and here's the best of my sharing this week:

• Game-changing books for marketers:  Nancy Schwartz put this blog carnival together, collecting posts from nonprofit marketers on books that changed their professional lives. I'm one of many with a good read on this list.
• Working the wiki: A Harvard researcher, disappointed in the accuracy of Wikipedia's psychology articles, has launched an initiative to improve them.
• Money for nothing and the books for free: The National Academies has decided to make all its books available for free. That's the good news. The bad news? They're all going to be in PDF, not ebook, format.
• Cooler tweets: 10 cool things you didn't know you could do on Twitter has all sorts of magic for you to try...like removing all the locations you attached to tweets, and other tricks. 
• We're all seekers: Reports surfaced this week that Twitter search is serving up 1.6 billion search queries per day.
• Delight me like that:  There's a lot of talk online about using your company's social media sites to delight your customers. Motorola's offering a 50 percent off discount on Bluetooth accessories on its Facebook page. That'll do it.
• YouTube mixes it up: Now you can use Creative Commons licenses on YouTube to allow others to remix your work, with credit, and leave comments with symbols, rather than writing a long screed, on YouTube videos.
• Play it: Tumblr users now can record and share music with SoundCloud, making the site even more versatile.
