There was a great renaming of newsgroups. I don't remember the year, but it was around 1987 or 1988. Before the great renaming, all newsgroups were net.* or mod.*. The mod groups were moderated. The old name for rec.bicycles was net.bicycle (yes, singular). I just found articles I posted to net.bicycle in 1986. I know I was reading it in 1985, too. I don't know why they don't have what I wrote then.

I'm pretty sure Jobst didn't join rec.bicycles until after the great renaming.

When did rec.bicycles become rec.bicycles.tech, r.b.marketplace, etc? I started very shortly after that, having finally got Usenet access- Internet access in general was limited pretty much to universities around here. Some of the same folks posting today were already here in the rec.bikes.* groups by then, and a lot of them have gone away.
I was in rec.bicycle long before it got split. I just recall that Bruce Hildenbrand was an activist for the split. He may know when that occurred.

August 1992. Here is the welcome post from Les Earnest:
I was reading Usenet back then, but not in rec.bicycles.* Around that time it seemed like most users were at universities, tech companies, and the occasional ISP like Netcom (anyone remember Netcom?) And some horrific header-mangling BBS gateways.
When I referred to the spoke/flange "load point", I meant the point where the spoke attached to the flange. A spoke is what is referred to as a "one-force member", meaning it can exerted only a single force, oriented directly on the line from one end to the other. Therefore, the point at which the spoke attaches (pulls) on the flange has a direct affect on the angle at which the spoke pulls on the rim, and therefore the lateral component (bracing force) contributed by the spoke on the rim.
Spokes do not exert any bending forces over their length, that is the spoke axial centerline is a line of action of pure tensile force. Therefore, "load point" is irrelevant. The effective origin of the spoke at the hub is the straight line extension of its centerline where it intersects the axle, Flange height and width only serve to confuse the issue.
Semantics or pedantics? Of course, it is only the angle of the spoke that matters. But the spoke is attached to the flange, so the location of the flange (and the point on the flange that the spoke attaches to) will determine what the spoke angle will be. The main issue in this thread is that whether the spokes are radial or crossed, or laced heads in or heads out, is splitting hairs in regard to spoke angle.
