Finding interesting tech news is something I have spent a lot of time on over the years. RSS subscriptions, Techmeme and before blogs got popular News.com have been three favorites. For tech news with a business development/commercial product development orientation I haven't found a great site.
But I find the community Quibb to be on to something really interesting. From the mix of members, via the links posted to the comments it is surfacing interesting news that gets drowned out from Techmeme & co.
