When it comes to ticket sales, it's just fair to take such measures. Secondary sales are nothing less of stealing. It would even make sense to only sell one ticket per person or to bind each ticket to a specific name and ID.
The only thing that's really unfortunate is the online sale system. The WASTE ticket shop seemed to have massive issues. Even though I was getting a good place in the queue, something seemed to have failed. Whether it was an old version of Java that my browser was running or a server error, it was simply vexing to watch time run out and my reservation expiring along with it. The info page said not to reload the site too often OR only in case something went wrong, otherwise you'd get kicked out. So the simple fact of sitting there and seeing that apparently with everything starting out fine, some tiny issue getting in the way of your purchase is incredibly frustrating.
I'd prefer to stand in line for half a day in front of some ticket shop rather than sit at my computer, watching what at first seems like a "working reservation" only to let the tickets slip through my fingers for whatever reason (i don't care at that point).
Right after this I got a ticket for the Lollapalooza in Berlin, but would have prefered to see a solo show instead. I guess with all these problems concerning sales, we seem to be in a time of change and experimentation. At least the live experience can't really be topped by anything and will stick with you for as long as you can remember.
