Mapping the world with tweets
A few days ago, I collected 30 minutes of tweets all around the world. I used the twitteR and streamR packages for this. The nice thing about those tweets is that they have geo-information associated with them. Not all of them, of course, but more than enough.
Let's see, what happens if we plot all the tweets at their respective position.

Isn't this awesome?! It's a map of the world - without using any map packages or stuff like that. Only half an hour of tweets. Of course, some parts of the world are seriously underrepresented like Africa and Australia.
Where can we go from here? We have lots of information available. For example, we can use the time stamp to see the world map "emerge" over time.
