It’s hard to even know where to start. This PowerPoint slide “explaining” Twitter’s new strategy statement is amazingly incoherent. What does the Venn diagram mean? What is the difference between the company’s scope and their competitive advantages? And what could “objective” possibly mean here? How is “be[ing] one of the top revenue generating companies in the world” a strategy? Could they fit the word “world” in one more time? Dennis K. Berman of the Wall Street Journal points out via Twitter itself that the slide includes “35 words, 62 syllables, 4 clauses, [and] 2 grammatical errors.” (He also retweeted a sentence diagram of it.)
Flickr was once one of the best places on the internet to find new Creative Commons-licensed photography, but since its takeover by Yahoo!, it is harder to search and to collect attribution for Commons-licensed content. (See this BoingBoing post for more info on how Flickr is broken in this respect.) The “Explore–>the Commons” tab seems to only search public domain images, or resources from institutions or organizations, neither of which are usually properly marked with a useful license type. The bookmarklet in this post from Digital Inspiration does a good job of making attribution easier, and Cory at BoingBoing has an update to another bookmarklet as well, although I haven’t gotten it to work yet. Librarian By Day has a helpful Flickr/CC attribution guide. (NB I have not always properly attributed here, but I’m at least beginning to learn how to!)
Wikipedia also maintains a list of public domain map resources. If you need to do a great deal of map data work, another good resource to consider is Natural Earth, whose maps include integrated vector and raster data.
