I was thinking in terms of a user having a portfolio, a topic (possibly several if they wanted to separate the subject matter of their work) which they could post to but to literally only show their work, as opposed to having the extra noise of comments that people may add as they see the posts and work.
The only way I could see that working would be to limit who could post on that topic to only the topic owner, and obviously mods/admin. This would prevent others from adding noise, but they could still like topics to show their appreciation of the work.
Idea is currently shelved
