This is a PERL SDK for Google Places. This SDK allows developers to access the Google Places API through PERL for integration with other applications and devices. The Google Places Web Service is a service that returns information about a "place": an establishment, a geographic location, or prominent point of interest using an HTTP request.
Twitter co-founder Biz Stone has just announced a new geolocation API that will be available to developers fairly soon (Twitter API profile). The new API, which will likely be rolled out in Twitter clients before being available on the Twitter site, will allow users and developers to add latitude and longitude to tweets, thereby adding a valuable new layer of meta information to tweets.
RhymeBrain is a service made to help writers, or anyone else for that matter, find rhymes for words, make new portmanteaus, and alliterate well. When writing with figurative language, or writing poems, such a tool can be very helpful for a writer who's currently stuck. It might also be helpful for such things as computer generated literature, but for that, you'd want a robust API with full access to the database. Well, you're in luck, because it does indeed exist.
