Moonbeam provides a simple way to keep track of
all your bookmarks in a central location, instead
of being attached to whichever browser you're
currently using. Its advantage over services like
del.icio.us is that the data is kept on your
server. Additionally, each bookmark can be
assigned an arbitrary number of metatags, so Web
sites that don't fit neatly into one category can
be given all the tags that apply, which also makes
finding them easier.
