I think any sort of featured project thing needs to be self serving. People love to talk about themselves. I envision it as something like this:
- Each month, a new (pinned?) nominations/voting featured project Community thread is made. It announces the current winner, perhaps quotes their post, and links their project thread. Optionally, their thread is also added as a banner to the site for a week.
- It explains that users can reply with one image up to 600x600 in size, and up to 150 words. Brevity is the soul of wit. And it’s more engaging.
- Users reply to the thread with their blurb/image as self nominations. People like their post. The most popular post wins (unless it’s disqualified / overruled by staff).
- Optionally, after x hours or 5 replies of self nominations, the thread is locked and pinned. This is to stop people from getting as burnt out on the process, as people will want to recycle their replies from last month, and anything far into the thread isn’t going to get the most likes anyway. Alternatively, there could be a reply from the organizer saying that self nominations are now closed, so please save your submissions for next month. That way discussion could still occur.
- When the new thread is made in the new month, it includes stuff about the winner. See 1. The winner may also revise their project thread OP if they feel inspired to do so.
I think something like this would be sustainable.
