Since Adriaan Tijsseling makes one of the Mac's best blogging clients, it only makes sense that he also has a slick RSS newsreader called endo that we honestly don't stay on top of as much as we should.With features like a custom Growl-like alert window which allows you to read snippets of feed items before actually bringing endo to the front, a powerful subscription manager, and a feature-packed download manager with options for adding media to iTunes and even BitTorrent controls, endo brings some clever stuff to the table with a unique UI. Upon opening endo for the first time, a short setup process allows you to enter users names and URLs to track activity and comments at sites like your Flickr account and a personal blog. The headline list on the left features favicons for your individual feeds to help you pick out items from different sites easier, as well as color labels for subscriptions and even a customizable summary + tag display below each headline. To summarize: if you want features and power - endo is a great choice.
I bring all this up again because endo was yet another app that is affected by the Safari 3 beta, which includes a new version of the WebKit rendering engine than many Mac OS X apps, including endo, use to display web content. Fortunately, Adriaan has produced an update that accounts for this fix, which you should be able to grab by starting up endo or heading over to kula software and downloading a fresh copy.
Another perk of endo is that, even though it's one of the most powerful and feature-packed RSS readers on the market, it only costs $17.95 for a license. Adriaan even offers a bundle deal that includes both endo + ecto for a savings of $10 at a mere total cost of $26.95 - those are some good deals for blogging + newsreading software.
