There's been quite a bit of hand-wringing about what London can do to top the Beijing Olympics, but with a little brainstorming it's not that hard to come up with a few things they could rub in Beijing's face do better than Beijing:

1. Instead of having protest-zones, have protest-free zones. Make almost the entire of London a welcome zone for protests of all kinds. In fact, the city should fund protests signs and banners, provide transportation for protesters, and organize protest forums. The more voices the better.
2. Party like there's no tomorrow. The BOCOG has been so uptight about the whole Olympics, and from my experience here it's pretty clear that the GPCR wiped out all notion of how to throw a decent party in the PRC. The national houses? Make them an afterthought to the parties thrown by LOCOG.
3. Stick it to McDonalds. We all know the British Isle's reputation when it comes to food, and this is a chance to turn that around. Invite culinary masters from the Continent and beyond to dazzle visitors with a night market of exotic snacks and fine dining on the Olympic Green.

There's three suggestions. Any more?
