Great, than we are a group of volunteers and start commenting in October in Italy. If we all can do about 3 comment per day this means the amount of comments but also interaction should be noticeable increase. If that works and writers comment back we can try another community for a few week. Can be also two weeks is enough.
For now I would say let's take it easy. It's a bit extra what we do and if you can't comment on a day it's no big deal.

Let's use #wewrite underneath the comments I noticed people start using it also those sho don't join the writing course.
