It would still be early if you jump on this platform right now. A BBM Channel with about 40,000 subscribers is far much better than a Facebook page with 100,000 fans. I know what I am saying unless Facebook decides to change its algorithm on how posts reach the fans. On BBM channels, reach could be over 50%, depending on when the subscribers visit the feed.
Download the latest Blackberry Messenger App and enjoy all the features of the BBM Channel. There is also a web App that can help you manage your channel from a web browser.
You can even promote your BBM channel with Blackberry officially, but you must have a very high budget to do that.
