The story of the open source notebook and to-do manager application Chandler is a long and complicated one, as we covered here when it arrived in version 1.0. It was originally started as one of Mitch Kapor's projects, but Kapor (the founder of Lotus) left it, and it took on new life as a community-driven project for Windows, the Mac and Linux. Now available in version 1.0.2, it's a powerful mashup of to-do list tracking, tickler alarms, note tracking, calendaring and more. Collaborative workers can also use it together to brainstorm, share project, event and calendar items, and track milestones. Here's a look at how it works.

In early October, Lisa wrote about open source mobile push and sync provider Funambol, and its decision to try supporting its services with ad revenue. Lisa felt (and OStatic commenters seemed to agree) that as long as the service was good, and the ads weren't intrusive, it wasn't a bad trade.

Today, Funambol released the results of its user survey regarding its ad funded mobile email service. The survey results echo some of the comments here -- ads that are non-intrusive, relevant, and respect user privacy are acceptable when subsidizing the cost of useful, free applications. It seems targeted ads, paired with the right services, could prove to be a solid market model.
