Collisions are a normal event on an ethernet network- that's the way Ethernet works- and the more hosts you have, the more collisions you have (unless you use switches). So it's the percentage of collisions that indicates a problem- rough rule of thumb says 3% or so is acceptable, but this depends on your lan and the type of work done: if you had 6 PC's and a server doing typical data input work, I'd expect to see near 0 collisions. On the other hand, if you had a large number of hosts all busy transferring data files back and forth, I'd expect to see a lot more..
This article was written when hubs were common and switches were rare. You shouldn't see collisions now.
