it will take a long time, no doubt about it. But it is at least starting. You have to bear in mind the huge sums that are spent on advertising. e.g. Daily Mail: Full colour page, guaranteed position, Monday, Tuesday or Wednesday = £53,676. That is ONE page in ONE paper on ONE day.
OK, you could argue that no-one pays rate card prices, but we're still talking a completely different kind of pricing level compared to few hundred or few thousand for a domain.
At least if they buy a domain they get to keep it. What use is the newspaper advert the following day?
I've a feeling that domains will chunk into a number of different price points:
1. Zero value
2. £xx - £x,xxx - names suitable for affiliate sites, brandables etc.
3. £x,xxx - £xx,xxx(low) - Generics with some (but not much) commercial use
4. £xx,xxx+ - Generics with a commercial use
5. £xxx,xxx+ Prime generics & category definers
Geos will fall into 2, 3 or 4 based on details of geo area; personal names into 2 or 3.
5 would be for extremely commercial markets and single word commercially applicable words: rent, debt, house, car. The sky's the limit.
