Here are a few of MarkaBoo's features:
* Bookmark not only urls, but also notes and files
* Create bookmarks via email
* Create bookmarks via MMS-capable mobile phones
* Commenting/annotation system
* WYSIWYG editing mode (via FCKEditor)
* Import from del.icio.us, ma.gnolia, or your favorite browser
* Atom feed support
Check out the RubyForge project at http://markaboo.rubyforge.org
or visit the application's site at http://www.markaboo.com
The current version of the codebase is 0.7.0.
I'm personally excited about giving the community the opportunity to
shape the features that will make it into 1.0.
Cheers,
