Count me in with the continuous people (running an experimental sender that is nowhere near ready for release, alas). I see the same sort of thing (6-7 hops or more in 20 minutes). I expect this will actually get faster with new news software (TMNN or C) that puts less burden on the news machines and makes people more willing to run fast transmissions. On the other hand, Usenet is a heterogeneous network and lots of readers are on sites away from the NNTP 'backbone'. This leads to an even more interesting phenonminon: those away from the backbone can often be presented with an entire discussion, four or five messages-worth, that came over in one big lump. This will probably affect responses some way or another: it might inhibit a good response, because the recipient thinks they'd be butting in on an ongoing conversation, or it might provoke a better response because the responder knows what's already been covered. --John -------------------------------------------------------------------------- John L.
