rssやatomより軽いシンジケーション・フォーマットInfo Bite List

Antone Roundyの提案しているシンジケーション・フォーマットInfo Bite Listはrssやatomより軽いらしい。

As a consumer, hopefully the tools you use support a variety of formats so that you can use whichever you want. You should use whichever format is offered by the websites you want to subscribe to. If they offer more than one, you should choose the one that contains the best information for your needs. If they contain the same information, you should choose the one that downloads fastest. When the Info Bite API is complete, it will contain unique functions to minimize the size of your downloads.
