Note that I didn't actually say they _were_ a directory, I said they were closer
to a directory than a crowded DNS tree (and arguably the classified hierarchical
section of sites like Yahoo _are_ close to your requirements for a directory) in
the services provided to the general population - a means of finding the correct
website content given some prior fuzzy idea of the organisation name or contents
of the content.

As an example, in a true directory I should be able to get a list of sites of a
particular class or similar characteristic - for instance, pubs in Sydney :-).
If I'm feeling thirsty after work tomorrow (, I can't do a DNS query
that will list out for me a selection of nearby watering holes but I can get a
VERY focussed and relevent list by going to Google and typing 'pub sydney' (go
on, try it!). Its not a set of unique links, nor is it a fully complete list,
and there are a couple of irrelevent links as well - but its good enough for my
purposes,  and much better that what a DNS query can give me.

(I tried both MX and ADDR lookups for '*pub*.*.au', but got back error codes
both times :-^),

Never said they were Mark - but I see them as a vast step up from DNS name
guessing - and if those stats you quoted are typical of your experiences, I'd
humbly suggest you try a different search site! :)
