Personally I'd like to see more time relevant results (or an easier way to search by date, instead of: adv. search/more options/date) When I'm searching for a computer problem how relevant is a forum post that was posted 4 years ago? I'd like to just quickly see if anythings happened in the last week/two weeks/month etc.
We've been doing similar things at Duck Duck Go (http://duckduckgo.com/) to these new Google changes. In particular, we put zero-click info, e.g. topic summaries, on top of links. We also also put an explore box with related topics above links. For example check out http://duckduckgo.com/?q=futurama
Our snippets and related topics are not algorithmically driven, however. Instead they are based on human edited sources, e.g. Wikipedia and Crunchbase (and many others). Consequently, they are more relevant and make more sense than Google's info. We also have more semantic properties, such as ambiguous keyword detection, e.g. http://duckduckgo.com/?q=apple, which of course Google does not.
