In all honesty, I probably do 1 in 10 searches on dmoz.
You and I obviously do wildly different searches. I appreciate that but I don't think that I'm alone.
I do a lot of research on topics (particularly information for my own websites), for which I find that DMOZ slates the major engines for search quality and finding what I need.
I regularly drop a link in threads on WebmasterWorld to a dmoz category and get a "hadn't even thought to look there!" response from a member. 99% of the time they've got what they need from DMOZ and not a search engine.
That's as much about educating the user on how to look for something on the internet as it is about anything else.
I stand by my contention that it's a useful resource for a lot of people. You may not be included in that bracket, and I'm sure you're not alone either.
But it has its place.
I agree with that. But 10% is still 10%, and that represents an incredible amount of searching.
