I made a Twitter-bot a while ago for HN, I find it useful and there's over 7000 people following it now. It's only new stories in the top 5 though, mainly to stop information overload.
I have a "reading material" Twitter list set up, including @newsycombinator, and I regularly scan this for this to add to Instapaper, which I then generally read when travelling.
Admittedly, the problem with this is that it means I'm a less active participant in the community here than I'd like to be.

Thanks for making this Rik. I use this as my primary feed. Works well.
