Snackr: a new way to get your RSS fix
Because it's an AIR app, Snackr is cross-platform and sports a look that won't feel out of place on your OS. Ticker speed and position on screen are adjustable, and you can force the ticker on top of your other windows if it suits you. Snackr supports OPML files, so it's very easy to populate with the feeds of your choice. It also minimizes to a tiny tab when you want to put it away for a while, and shows a preview of each story you click on, instead of going directly to your browser. Snackr doesn't interrupt what you're doing unless you want it to.
All in all, this is one of the most useful, best-designed AIR apps we've seen yet. It's essential for heavy RSS users, or anyone who wants to stay on top of breaking news. Don't ditch your full-featured feed reader, by any means, but do supplement it with Snackr if you're looking for a faster, more dynamic way to consume information.
