Incidentally, I have just been on to GB to look at this thread - 16
posts

While on urg - 24 posts.

I haven't time to see whether the missing posts are all to do with time
lag.

And re ease of use - in GB, all the posts in the thread are in one long
chain arranged according to time of arrival. In a newsreader, all the
posts are sort into their subthreads, so you can read all secondary
responses to one answer before reading the next answer and its secondary
responses. Saves an awful lot of dodging about trying to work out
exactly what point someone is responding to.
