- Realtime messaging and XMPP. After some initial experiments, I'm really excited by the possibility of visualisations driven by realtime data feeds. I like the idea of XMPP, and although scaling it out gives me the fear it's a fear I'd like to confront in 2009 on a real project.
- Custom cartography and up-to-date maps. I'm a long-time cheerleader and supporter of the OpenStreetMap project and the project is reaching a level of completeness and complexity that competes with commercial map providers. I'm looking forward to writing tools and maps that work with OSM data in a way that just wouldn't be possible with Google-Maps-style mapping APIs or would require data well out of the budget range of most of our projects.
This post could probably use some supporting links, but I thought I'd get it out there before my first week back at work ended. Happy 2009 to you all.
