Child care, design and subtraction

Great ideas come out of the SXSW festival in Austin, a tech/music/film event.
Jeffrey Zeldman, an interaction designer, proposes a couple of disparate ideas worth your time.
Zeldman, who Tweeted frequently during the recent conference about missing dinners or events because he was playing with Barbie dolls with his child, throws out the idea of a child-care co-op for future conferences. It's a wonderful idea that can help broaden the diversity of attendance at similar events.
And he concludes the post with links to a couple of videos about design. My favorite part: Michael Lopp of Apple talking about how good design is the taking away of features, not the adding of more gizmos.
The tie between Zeldman's ideas? Usability.
Go there.
