RSS is for Nerds
About the App: Like Zite, Taptu is also using algorithms to filter out news you'll like. But this app does it in a more overt way: in Taptu, you type in an area of interest (e.g., Architecture) and its crawlers go out into the Web to search for news about that topic. Unlike Zite, there's no learning period: you get your "personalized" results as quickly as you type them in. This doesn't do as much to solve the discovery problem, although Taptu's staff offers lots of pre-curated channels that are pretty expertly assembled.
About You: If Taptu is your thing, then you probably consider your RSS reader pretty exhaustive, and you like managing your reading sources manually instead of handing over all the power to the app. As journalists, we like this one, because it does a fairly good job of letting you digest large quantities of news at a time by grouping sources into topical "streams." You think the UI is pretty enough.
