I totally agree with you that communities are a big step forward for the steem world. When I look at the quantity of new communities that have been created, I believe that this is due to the hype of the "new" since people just want to create one for themselves to see how it works.

In the long term, with the number of active steem users, the quantity of communities with real interaction will be quite limited I believe.

On the other hand, communities may also offer a place of exchange for small groups of people with similar interests.

P.S: I just checked your profile and it seems we share the same home country ;-)
