There's a debate on WW whether the ODP is shrinking [webmasterworld.com] or not.
austtr asked a question, and it seems to have been ignored:
Why do we continue to rehash the DMOZ saga over and over again, with the inevitable angst that always seems to accompany such discussions? Because.. the belief that Google rewards sites that have been able to make it into DMOZ.... right?
Why not challenge that assumption and try to establish if Google does in fact [still] reward DMOZ listed sites?
1) In my experience sites not in DMOZ get the same amount of traffic as similar sites not listed in DMOZ.
2) [assuming DMOZ is inactive] why would Google continue to give extra credibility to DMOZ listings if that continues to be the case?
Let's have this GOOGLE question answered without the heat, please.
When I do a link back check in Google they don't even show up.
I'm not too certain that is an indicator of anything. If I were a search engineer and I wanted to protect those properties that I deem to be of importance, I'm going to do what I can to stop you from reverse engineering. One of the simplest things I can do is make it appear as if the ODP is not passing any value. ;)
I'm sure the Editors could vouch that submissions have died off over the past year or so. They are probably getting more quality submissions now that the word is out that a listing in the ODP is no longer of value. :)
