What if there was a Web service similar to plusplusbot.com that could collate car registration numbers in the context of good or bad driving. If you spotted a bad driver you can tweet their registration number with x hashtag (possibly including location) and a positive or negative modifier that would then classify that number.

If critical mass is achieved you could have a very useful resource that could help law enforcement in finding bad drivers and encourage good drivers through promotions.

Potentially insurance companies can use this as well to find out if potential clients are good or bad bets.

What if an online application existed that simply helped people recommend movies, books, services to others. The interface and premise should be really simple: In really big type, two boxes and a submit button:

If you like [.......] you will like [........] [submit]

The database will create the connections and all sorts of interesting visualisations of these pairs would become possible. More importantly, the adjacent connections would also be interesting. In reality, strings of concepts could become connected and help people find content, Web sites, brands – anything really – based on what they like and what the swarm likes.

iPhone + twitter =

Wouldn’t it be great if twitter was able to draw more metadata from tweets sent from smart devices like the iPhone? For example, it could check location, weather and even snap a picture to accompany your tweet. You could set how much of this information would be public.

It strikes me that the next evolution for twitter would be able to make the actual tweets more layered. Smart devices might be the way to do that.
