One thing I'll say for Hogan is that he does tend to give the old guard their props. Those 'reasonable robots'? I wouldn't have been at all surprised if one of them had been given the moniker 'Daneel'. No Giskards, of course, given the publication dates.


On Edit: I just did a double take when I realized that -- assuming I can properly count my fingers -- R. Daneel Olivaw is Asimov's most frequently appearing character. Well, in his novels at least.
