I think the bigger problem with Google's UI is that the top links to Google's top-level categories do not keep your search terms. Only the left links do... In other words if I search the web for "Afghanistan" and then realize I actually want news article search results, if I click "News" at the top I have to re-type "Afghanistan". This is terrible.
That functionality -- especially in regard to the news tab -- drives me nuts. Over and over I click the top news tab forgetting I have to click the link on the side and lose the current context of my search.
At first I just assumed it was a bug since the other tabs kept the context of the search. Then after a week of the same, I looked into how to flag the issue so it could be fixed and low and behold I found it was a product feature (or non-feature).
Its such a strange UX decision that I have to assume that it is driven by revenue generation or some other metric rather than good user experience.
I cannot agree more. Has it always been like this or is this a recent change? I thought I remembered a time in which clicking "News" did keep your old search term but I cannot be sure. In any case, this behavior has been a bane to me since I discovered it.
