I avoided suggesting anything because I don't want to pretend I know the answers. Automated aggregation of headlines from Coindesk would be an interesting experiment.
I guess my suggestion would be to have a place that encourages the posting of any interesting development that people come across via other bitcoin hubs. And perhaps seed it somehow, r/bitcoin spies, Coindesk, whatever works.
I think there are two different kinds of bitcoin news: current events, and new inventions/software/products. It would be nice to have them split, but it might not be practical - it will depend on whether new threads get created in drips or a torrent. r/Bitcoin seemed to work fine with everything jumbled together.
