We read HN mostly for the Rate my Startup posts and the announcements of cool new apps. We thought, "wouldn't it be nice if there was one place that announced those, and didn't focus on politics and funding like TechCrunch?" and so we made Apps Only - https://twitter.com/#!/appsonly. Apps Only covers only new apps, with an extreme focus on product.
We only tweet something if we've used and loved it ourselves. Enjoy!
PS. We is https://twitter.com/#!/appsonly/curators
