This is very similar to something I've been looking for/thinking of building for some time. I took a look around but browsing was very slow for me so I'll just ask here; do you have any plans for training filters? That is, feeding it data about what sort of thing you read (and on what basis; software announcements I might click on daily, but if I haven't checked in for a month I'll only check more serious articles / deep discussions) to get personalized results.
