Intuit ratchets up the stakes with a VAR partner strategy for developers. But Intuit has NOT done a good job in the online database game - their Quickbase product is pretty sucky, the last time I looked at it.

remember the milk is a cool online task list service. But it seems to me that their user interface has many design flaws.

Despite these flaws - it's still a powerful tool, with some cool sharing features that make it a pretty good solution to light-weight task list sharing.
