New VOX Feature Suggestion
I think features like QotD are too easily overlooked so I came up with Shared Post idea to encourage participation as well as enforce social connections.
A shared post is a post that is posted to one or more blogs of people belonging to a group (i.e. neighborhood, friends). Since allowing members to compose shared posts could lead to abuse as seen in Orkut, I think shared posts should only be sent out by the system (Vox). Shared posts can be seen as a shared experience, an event if you will.
Shared Posts are implemented by posting a simple envelop to each blogs which is 'filled' on-demand with latest results. Shared Posts are not 'editable' by bloggers. Instead of editing, a shared post contains a simple form at the bottom to 'contribute' to the post. Shared Posts can be used for QotD or other group activities. Since shared posts can cause feed to be constantly updated, I think shared posts should be invisible to feeds to minimize this problem.
One problem with implementing QotD with shared post is that individual QotD answers can get pretty long. This is not bad but, if spontaneous wide participation is desirable, I think Finisher-style shared posts are more appropriate. With a Finisher, users are asked to finish a sentence like "If I had a million dollar, I would..." With most answers taking up only a line or two, Finisher shared post can look like a text chat.
