There is the strong suggestion in this thread from very knowledgeable people that the DMOZ listings may play a role in the Google algo; and
 Google is utilizing those listings in its own directory; and finally
 There is the observation by many that the DMOZ directory is/has been/may-continue-to-be outdated.
So, all I'm saying is that given the connection between DMOZ and Google, it may be to G's interest to make some effort to get ODP back on track again -- they've got the bucks, the brainpower and the reason to do so.
Otherwise, the impact of DMOZ listings on the algo are not going to be generally accurate, which may create some distortion to the resulting SERPs. Garbage in, garbage out.
