We might consider adding this in a future version as a filter or something. Houston is not really designed for content-heavy installs though. It’s purpose is to fill the role of an internal twitter feed with team members (etc) posting short status updates rather than hefty posts. So we’ll see..
I’m wondering if anything came of this? I’m not really wanting content-heavy stuff, but as a simple tool for sharing stuff as a team, sometimes sharing an image is very useful. Far less effective if you only share a link to go see the image. Much better if you can just insert it right into the post.
