Seth's list of Web 3.0 Applications

In Seth Godin’s latest post Let Me See, Seth lists out 18 ways that you could mashup data and present it in ways that are useful and very powerful.

This got me thinking: Did he just post 18 ideas for startup companies? Yes, I think that he did.

So, what ideas do you have for mixing contextual data? And how can this be delivered on mobile devices, like the iPhone or the Android platform?

Post your thoughts in the comments.
