The recently released Google API is having quite the inspirational effect on developers. Submitted as evidence:

• Googlematic lets you search Google instant messaging clients, currently AIM and MSN Messenger. Basically, you contact the user "googlematic" on either system and send it a search term. It comes back with the top result, and the "more" command will let you retrieve the top five results. I'm going to give this a try through Trillian tomorrow. Think of it as SmarterChild for Google. My question, of course, is how could a library use this? I suppose if your site was indexed well enough in Google, you could use it to let patrons search your site via IM. I'll have to think more on this one.
   
• Google2RSS is a command-line tool that runs a query using the Google Web API and spits out an RSS 0.91 feed containing the top 10 hits. Combine Google2RSS with a task scheduler like the one built into Windows 2000/XP and the Radio Userland upstreaming facility, and you have an automatically generated, regularly updated, topic-oriented RSS feed: collaborative filtering courtesy of Google & the Internet, pushed to a desktop near you by Radio!"
