The August edition of The GNOME Journal has been out for a few days, and it's worth checking out if you want a behind-the-scenes look at GNOME development. I've mentioned Tinymail before, and if you're a developer, the article on it is a good read. (Tinymail is being developed as a sort of object-oriented framework instead of just a library.)
Lastly, the interview with Davyd Madeley is pretty interesting:
In your opinion, what should be the next GNOME big steps?
Integration and collaboration. If I have a Bluetooth device, its useful functionality should be integrated with my GNOME applications. My Nokia 770 (or the one I wish I had) should be able to seamlessly integrate with my GNOME Desktop. Not just by syncing data with Evolution, but also at an application level integration. The Jokosher remote is an interesting example of this.
Collaboration is somewhere where we can really get ahead of the game. Collaborative Abiword, collaborative Inkscape, these applications are really pushing the limits with how people expect conventional applications to function. The way we work is undergoing a paradigm shift, in that we no longer all work together in the same office and sometimes, there is no office at all. The ability to collaborate in the same basic way but over a network is seriously a cool thing.
