No, it hasn’t. Why would a BP plugin reinvent blog posting when that’s the main purpose of WordPress?
Buddydev.com has a group blog plugin that takes advantage of standard WP’s blog categories:

Something similar could be put together like that for members instead of groups.
Great idea @r-a-y, ala Ning with front end posting and possibly using each member’s username as parent category or even post type.
@Shonnaedwards one way of doing allowing members to post articles without a plugin is by giving new users the role of “Contributors” or above just like many WP multi-author blogs thereby allowing members access to backend to post articles.
For a plugin solution, try this one https://buddypress.org/community/groups/one-quick-post/ where members can post from the front end and you can keep members/users’ roles to suscriber level.
mercime, thanks for adding that extra info! Forgot to write about WP roles and frontend posting!
