Yes. There are several reasons behind this. First of all, most people are more likely to be motivated by a project manager and they be motivated to join the community. A tribe project manager shares good news and plans through posts. Which attracts more people. A project manager is important person for all and also a project manager's post is related to tribe and trend on hive's all tags after getting lots of votes. For this reason, it is easy to spread his word to everyone. We are deprived of this facility because of our project manager's negative reputation and not posting.

People are probably more attracted to hive and hbd. They use the hive.blog site more and join the tribe where the most rewarded posts are shared. The proof of brain tag or tribe is not the highest amount of hive and hbd rewards so they are not very interested. What makes this tribe more interested is the POB token that they often don't see.
