It's been a couple months since the purchase, and so far, I haven't seen anything other than GameStop adding a little "Flash game of the week" section to its newsletters, linking to Kongregate. Well, that, and the removal of "beta" from the Kongregate header, as well as adding a little "part of the GameStop network" in a little corner of the page. I'm a mod on Kongregate and I haven't seen anything really go /bad/. Sure, the badge selections may seem a bit bad right now, but those are mostly just the games that are popular, and as for those that weren't... well... there have been far worse, and GameStop doesn't really have any control over what gets badges anyways. They may be related to the resurrection of Kongregate's newsletter, though, but that's a good thing if anything. The promise of some monetary/discount-based badge-related rewards hasn't been spoken of since the purchase, but that was always just wishful thinking anyways. All-in-all, the only bad thing I've seen has been the addition of non-skippable ads, and I have no idea if GameStop had anything to do with that (In fact, I'm not sure if I've seen them in a while, so they might have gotten taken down).
