(Just adding my kilobyte to the total... 8-) For those readers of comp.sys.amiga who do not read news.groups --- Brian Reid just posted his monthly USENET usage summary, and, guess what? Comp.sys.amiga is climbing to the top, both in volume and popularity. Last months estimated readership was ~8500 (if I remember correctly), this month's is 12000. (Yes, UP 40%!) New hosts must have started getting our newsgroup --- Comp.sys.amiga also appears in the top 40 list of newsgroups with high propagation ratio (97% for comp.sys.amiga). Last month it wasn't on that list. Comp.sys.amiga is also the newsgroup with the highest volume --- Apparently 3 Megs have been posted to comp.sys.amiga during May, at a cost of $1.20 per reader. 6.3% of news readers read comp.sys.amiga. [For comparision, 7900 people read comp.sys.atari.st, 15000 people read comp.sys.mac, and 22000 people read comp.sys.ibm.pc.] Ali Ozer, ali@rocky.stanford.edu

Ali, this is not entirly a good thing. If you look, comp.sys.amiga also has the highest cost per reader. One needs to consider measurements that show the value of the group to it's readers and also the cost of the group to the sites that transport the material buy have no particular interest. Number one is a very obvious and precarious position. I'd be much happier to see us down around number 10-20 in every measure execpt readership... It should also be mentioned that Brian's readership estimates, while the best currently available, may or may not accuratly represent the real world. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
