Suggestion :

When someone vote or comment it will show on the top of the newsfeed again.

Should be able to add a widget on index page just for admin to be able to ask a question to the whole community ? :) 

It would be nice if we could upload pictures or video, just like if we were adding a status update, so people can ask questions about a picture or video. 

I would like this so I could have photo contests that people can vote on.

Today I was doing some minor changes to my site, and looking at questions plugin I tought it would be nice if we can have another tab added to existent ones(all questions, friends questions ...) that shows most voted polls. Like on Oxwall default links plugin(most commented tab). If there is a lot of activity on the site, polls get lost very quickly with other stuff and don't get the desired attention/votes.
