First off, MAJOR props to all four guys in that match. They put on one hell of a show out there and while it was overshadowed on the card and took place after some other great gimmick matches, I'm still going to remember that one fondly. I have been an Edgehead for a long time, and am obviously happy with the result. He is one of the most gifted overall workers with the rare combination of great ringwork and fantastic mic skills, and deserves a lot of credit for what he brings; not to mention how dedicated he is, to the point where he's battled back from career threatening injuries. The raw emotion in his face when he was climbing the ladder, even before grabbing the belt, speaks volumes about how seriously the guy takes his career and how much his accomplishments mean to him. Hell, you could even argue that he "broke character" by "giving it away" when he wasn't all the way up the ladder. It was a nice moment, especially given that a year ago, he probably wasn't sure he'd ever even have another match. Very interesting that he made it to 10 before Cena, though.
Kane's reign had gotten incredibly stale--months ago. His micwork was fun at times, but his matches were incredibly dull. To people complaining about how the reign ended, Edge himself had a good jab at the kidnapping plot, saying on last week's Smackdown that he hoped people would forget it ever happened, and while Kane may have looked weak backstage, he was strong in the match and didn't go out looking like a "pansy/pussy/whatever". A gimmick match was arguably the best way to take the strap off of a guy who was just built up as unstoppable. Think about it that way.
In response to Little Jerry Lawler's suggestion that matches with Edge would test Ziggler's potential for the main event: I wholeheartedly agree that Ziggler is an excellent choice for a feud with Edge, and Edge would be a great guy to cement him there. Ziggler faced Edge in a Bragging Rights qualifying match on Smackdown and has unquestionably proven this already. This match was absolutely fucking EPIC, and I would love to see a sustained, multi-match feud between the two. In case you missed it:

Not only would I call it PPV quality, but separately, Ziggler has been involved in arguably some of the best or at least most entertaining PPV matches in the past several months, as well as some fantastic TV matches. I am an incredibly huge mark for both of these guys and think that they could create something magical. Regardless, Edge is great at putting over new talent and making people look good in the ring even when they aren't (he didn't mesh well with Kane, but the plodding monster style is difficult for anyone to work with). I'm guessing he'll have some matches with Del Rio and Swagger before all is said and done, possibly a cross-over TV match or two with someone from Raw (Miz?), and hopefully Ziggler gets at least one match with him before all is said and done.
