The breeze coin project has been making consistent efforts in the marketing and promotion of the project, but I still believe that it could be improved upon as there's still several frontiers where the project could be promoted to help increase awareness and bring more persons on board.
I don't know what improvement you expecting from project team. Promotion means not just tweets, FB, etc. Main thing require here is use cases, then only coin/token will be in use and will get promoted automatically.
Team mentioned that many more use cases will be there, so I think they are on right path.
You mentioned a very good point, but even as much as the project increasing her use case is very important for promotional purposes, its also important for the project to go about telling users and people in general, what they have in store. It's possible that the project has an excellent use case, but people are not aware of it.
