Everything that improves the steem ecosystem and features is good not only for this community, but for strengthening the idea behind steem itself, "reward users for the content they create and share with the community".

3 months is actually little time, I am about to be 4 months old in steem and it seems like it was yesterday the day I joined, besides as you mentioned in the articles, important changes such as this should never be rushed.

With the communities feature I think we will have much more engagement and quality comments all around, it should certainly increase the value of this project.

Cheers!
