Speed Up WordPress Using Google’s AJAX Libraries API
Or, in plain English, it should make your site load faster. It could also make other people’s sites load faster too, if they’re also using this plugin.
Any WordPress themes or plugins that load any of these libraries via enqueue_script() should automatically take advantage of Use Google Libraries.
Why not give it a try?
There’s nothing earth shattering here, but my goal was do one thing and do it well. You can read the documentation and download the plugin from the Use Google Libraries page in the WordPress Plugin Directory.
