You can say this is a reincarnation of TTCupdates.com (by Brian Gilham), because it is. TTCing aims to increase awareness of the current state of TTC services, be it positive or negative, by bringing the "conversation" directly you: conversations about delays on the subway, shuttle buses, or an awesome on-time streetcar. An informed rider is a happy rider. TTCing is and will always be a free service.
TTCing is based on TTCupdates with several new features and tweaks (the biggest one is that TTCing is not limited to just the "#ttcu" hashtag, it will pick up any tweet that has "ttc" or "#ttcu"; behind-the-scenes, TTCing includes tweet scoring algorithm, mood-detection, route/station/bus number/stop-detection, and duplication checks), and is managed and maintained by Andrew Young (@andryou
