There are a lot of advertisements in the network about the project. But the community on the forum is almost none. No interest in the project or there are other reasons interesting.
Most of the interested ones are in the Telegram group. Discussions are mostly handled and tackled there since it is easier to send and inform message in a group.
That's right. Try to visit their telegram you will see how manty people are supporting Boosteroid. Those supporters want to have a direct contact and direct connection with the devs and admin that is why they are more active on telegram.
