I can only agree with all the above. The nature of Arch, and free software in general, makes it very hard to track the number of users. Commercially, 'number of users' can be a measure of success so people go to great lengths to keep tabs on how many users they have (or they have an even simpler metric - number of purchases). Not so here, since no one is having to 'sell the numbers' so to speak. Also, bear in mind that single users could be running lots of instances. I run four machines with Arch on them, all with different IPs.
