Another thread about soccer/football got me thinking. One thing that is popular with American baseball aficionados is scoring. It involves recording the lineup for a game and recording details of each at bat. The N900 would allow a database for all the games you scored to be built up over time.
That's about all I know on the subject, not being a baseball fan myself, but I thought I'd throw it out there.
i was thinking a little more retro looking... using with a sketch option to score it yourself... and just really providing an interface to archive, search dates, export to pdf, publish to a blog, etc.
But if anyone knows of a good open api to relevant team stats (rosters, current player stats, player numbers, positions, etc..) I would love to integrate that info. And when I say open api.. i do not mean web scraping.
