Everybody and their mom wants a redesign for DD.
And yet, it seems to work.
I'm not opposed to a redesign, I just am unsure what it should look like. And I'm sure even more people will hate whatever it does look like and nobody likes change (see Facebook, et al)
It definitely works but can be much better. Its not just a question of the design, but you can greatly increase the functionality with a redesign(search, your ad serving and tracking, comment system...)
Does "not being opposed to redesign" mean you are willing to pay for one? I can put you in touch with a good design/development team if you want. PM if interested.
