I posted about his in the feedback thread as well.
All site pages load considerably slower. Careful observation shows that it's the "account" portion in the top nav bar that takes longer to fully load; I assume it's due to the unbundling of games that makes the account "heavier". To me that's another negative side-effect of GOG's decision, a side-effect they either didn't think through or don't particularly care about in hope that everyone will jump on the otional client.
Also, since at least yesterday, I have to log out twice before I'm actually logged off - not sure if that's related to the unbundling, but it started very recently.
Seems to be a lot of churn going on not limited to game packaging/bundling issues. The entire website really needs to be updated with "live beta" in the title it would seem lately. I'm glad to see progress being made, but would prefer to see it without complete loss of quality control. Seems to get worse each day, making it more and more difficult to see it as temporary growing pains.
What bothers me though is not changes of which I'm mostly in favour of, and not necessarily the breakage so much, but the unintentional self-sabotage that occurs as a result of it being so customer visible and on the rise. For those of you familiar with tracking the development of a Linux distribution, the GOG website feels like Fedora Rawhide at the moment while what would make more sense would be for it to feel like Red Hat Enterprise Linux. :)
