Rereading this thread reminded me of how there still isn't a killer app for feed reading.
Newshutch had potential and in fact was overtaking both Google Reader and Bloglines as a third option before it's demise but in this day and age, feed readers went from a sprawling collection of offline and online offerings into Google Reader for online and Feed Demon for offline with Bloglines retaining it's old position.
It's scary how market monopoly drives innovation. Here we are where people have already created new tweaks to rss reading like twitter/friendfeed layer, magazine lay-outs and netvibes/igoogle mini-tabs, a scrolling ticker and yet no individual has yet tried developing an Outlook for rss readers.
Contrast this in the past where there was nothing going for rss readers except the aesthetic and the stability common in any programs and you got NewsHutch, an online Newspaper lay-out who's name I forgot, Netvibes, IGoogle, GReader, Bloglines (Old), GreatNews, Omea Reader, Sage, Wizz Rss, GreatNews, This ad-ware RSS reader with a green theme, this offline RSS-reader that highlights your RSS based on your preference, RSSOwl, RSS Bandit, etc.
All pretty much adding features or taking away without really offering anything new just to get ahead of the RSS Reader race.
