One problem remained: How would I configure the bookmarklet for a given library? Reynan suggested a geographical method: Request (or discover) the user's postal code and map from it to the nearest library on the vendor's list. That was plausible, but the mapping wasn't readily available. Then a laughably simple solution presented itself: Generate a list of bookmarklets, one per library, and blog it. A user who visits that blog page and finds a local library there can drag its link to the toolbar to install the bookmarklet.
Thus a new service, potentially useful to millions of people, was deployed by blogging a Web page containing 900 links. The meme spread quickly in the petri dish that is the interconnected blog network. My published RSS feed spread the news to my subscribers, who passed it along to their subscribers, and soon the blog indexes picked it up and spread it even more widely. By the end of the day, the technique was verified to work with many libraries in the United States. What's more, it had mutated. Reports came in from around the world about adaptations that worked with library systems from other vendors. These mutations, packaged as HTML links, propagated through the blog network. People from Syracuse, N.Y., to Sweden found links in their RSS readers that could be installed and used immediately. [Smart Mobs]
