I have been looking for ways to speed up MyBlog editor loading and Google Gears caught my attention. Google Gears is basically a browser plugin by Google that provide additional functionality to your browser, among other things, caching files locally! Bingo.
To get stright to the point, we have already implemented Google Gears support in our internal release. All javascript, including tinyMCE, css and images files will be loaded from your local cache. The editor now loads significantly faster and I am sure you will be pleased. We'll run a couple more test and will make this feature optional. I can't wait to roll this out!
