I think the biggest future potential hurdle with this move is that the brand "ReggaeJAHM" is very much Caribbean, both in the name "reggae" and also the most high "JAH." I think the base for hip-hop content could potentially come from folks who have no idea that reggae and hip-hop are connected, especially potential posters from the USA.
With the name of the token being "JAHM," it has a very Caribbean feel to it, so that is my main concern. I like the term "MOBO" (Music Of Black Origin for you non-Jamaicans), it's very catchy but it encompasses much more, and could send us on an entirely different course. I think it's all going to come down to branding, and unfortunately or fortunately there is definitely a Caribbean dominance with the branding.
Food for thought....... Bless up!
