I don't agree, I think it's fast evolving and by making a good community you can always attract people. Most users don't care about features, they care about being seen and ...
Not even the whole BCH community uses Memo or member. We have just over 100 users a day. Some may have multiple accounts.
UX is not very good and Memo is closed source which in my opinion is slowing dows its development. Even so, I believe there's a lot of unseen potential here to be utilized.
