Static content in a community is primarily for newcomers.
Once they’ve read it once, possibly twice, they don’t need to read it again.
The problem is when areas that should be dynamic (blogs, popular discussions, or announcements) feel like static content.
When this happens, you’re training members to ignore areas of your community you planned to keep updated.
For any dynamic section of the community, keep it updated. If this doesn’t happen organically, manually update it with new blogs, discussions, or announcements on a regular schedule.
If you don’t have the capacity or volume of contributions to keep it updated, close the area down and redirect attention to other areas. Blogs and announcements can easily appear as discussion posts if there isn’t enough activity to sustain them alone.
