MyBlog is a popular blog component for Joomla. Unfortunately the latest update is 3 years old, and the component shows is age. The authors are claimed at launch of the current version, that "It's refactored, cleaner code now fully supports Joomla 1.5 which, among other things, allows easy integration with JoomFish."
Humm... I have a separate opinion on this issue... but I managed to make it work nearly perfectly (translation wise) in a multilangual environment. The content itself is easy to translate, since MyBlog uses standard Joomla contents, so don't need extra content element rules to be translatable via JoomFish. The attached content element is for translating tags. Unfortunately if you want to translate more you need to hack in to the core of MyBlog. Can be done, but that's another story.
The content element you can find there was tested with MyBlog version 3.0.332, Joomla 1.5.22, Joom!Fish Version V2.1.3 (Twinkle), and can be seen live for example on Aquascaping.me.
