Well, that depends on your newsreader, actually. Rob is indeed correct
about what he thought he saw. :) Most newsreaders don't have a feature to
coalesce groups in a hierarchy into a single virtual group, but the LUGNET
web interface is magic and can display groups both normally and coalesced.
In fact, when you look at the root homepage www.lugnet.com, you're seeing
the last (most recent) few articles of the entire contents of 692 lugnet
newsgroups all coalesced into one big virtual group.

Right. Yup, you did see it there. If you look at
http://www.lugnet.com/robotics/
you'll see the 4 most recent message in lugnet.robotics and its subgroups
(as if it were one virtual group containing 17838 messages), with links to
get more articles, of course. If you look at
http://www.lugnet.com/robotics/?n=*,-20
you'll see the 20 most recent messages in lugnet.robotics and its subgroups
But now if you look at
http://www.lugnet.com/robotics/?n=,-20
then you'll see the 20 most recent messages in lugnet.robotics only (not
counting any of its subgroups).
The syntax of the n= parameter (n='news') goes like this:
?n=[*][xxx][,[-]yyy]
where xxx is the initial message number/index, and yyy is a delta (i.e., a
count of articles to display). If yyy is preceded by a minus sign, then
the delta is negative and the article display counts backward in time. If
yyy is not preceded by a minus sign, then the delta is positive and the
article display counts forward in time. If xxx is preceded by an asterisk,
then this means that xxx refers to an article index in the virtual coaelsced
group rather than the specific group. Other examples:
