Why Endo?

Mac users might be interested in this. Stumbled on this while reading the daily RSS feeds about RSS feeds. From the developers of the MacOSX desktop blogging client Ecto comes the RSS reader and aggregator Endo. But what is Endo?

Like Ecto, Endo was built for the Mac (specifically MacOS 10.4 and higher). And it has the following main features:

Endo enables the user to group posts and articles.
Endo enables the user to customize or specify how groups can be viewed.
Endo enables the user to search for an article using the filter or a feature called Spotlight, which uses metatags to search and retrieve an article or post.
Endo enables users to manage posts and articles with enclosures (and torrent files) via SmartDownload, which download enclosures in the background enabling more efficient retrieval of posts.
Endo enables the users to flag, blog (via Ecto) and bookmark articles or posts.
Endo can be customized further by using plugins.
Endo can be synchronized

Additional features include but are not limited to the following:

# First time user assistant guides you in setting up endo
# Subscriptions can be configured to notify you when new articles arrive
# AddressBook support
# hCal microformat support. Add events to iCal!
# Custom stylesheets
# Download images in the background for later offline reading
# Mark differences in edited articles
