Thanks for asking this question - it's been something that's on my mind the past couple of days.
It seems to me that quite a few of us enjoy using Blurtit to help people out by answering their questions - but the current layout of the site means those questions are sometimes a little tricky to find.
Currently, the best way to find unanswered questions is to go to www.blurtit.com/topics and then clicking on the "unanswered" tab on that page.
That will take you here:
However, we're considering changing the way the feeds work - in order to display the most relevant stuff in a way that's easy to find. So please comment and let me know how you'd like the site to look/work and let's look forward to building a better Blurtit together :)
