Dear Tim - an important piece of work. Congratulations to you and your team. By the way, The Innnovation Hub is Africa's leading science and technology park and home to a number of tech and business incubators including mLab Southern Africa, Maxum Business Incubator, Climate Innovation Centre. The Innovation Hub (www.theinnovationhub.com) is different entity from The Hub (I am sure you are aware of that). What is however interesting is that each of past series of this map, there is no mention of The Innovation Hub, as a tech hub. I am hoping that this input is useful. Alternatively, a criteria for what qualifies as a tech hub would also be useful.
