#citytalk is a monthly series of tweetchats discussing urban trends, and was launched by This Big City and Future Cape Town in January 2012.

A tweetchat is just like any other discussion, except it happens on Twitter! If you’re already on Twitter, simply login at the designated time, follow the #citytalk hashtag, and make sure you include the hashtag in your tweets if you want to join in. If you aren’t on Twitter you can sign up here to join the discussion, or you can follow the discussion without joining Twitter by clicking this link.

The date, time and topic of each discussion will be published on this page, or you can follow @thisbigcity and @futurecapetown for updates.

The next #citytalk will be hosted in June with the BMW Guggenheim Lab. Details to be confirmed. The discussion kicks off at 7.00PM London BST / 8.00PM Cape Town SAST / 2.00PM New York EDT and will last about an hour.
