Yep. The old blue on white background strip was easy to look at. The new color never looked good on Blogspot. Sometimes a single bad design choice can tip the balance between making something pleasant to use, or not.
An example: I upgraded my version of Open Office a month ago, for the first time in 3 years. There was one single change they made with the margin color in the word processor so when the left cursor is sitting at the left margin, I can't see it very easily. Because I move around documents a lot, and let the cursor sit while rereading, this is quite irritating. After a month, I've started pasting OO document text into Wordpad for editing, and repasting them into Open Office when complete. I sometimes wonder if a spy for Microsoft was behind that margin color change.
Another example: I only started using Open Office because Wordpad was similarly crippled by Microsoft a few years ago (starting with XP service pack 2, I think). Whenever you save a document, the page view changes so the cursor's at the top, also irritating after no problems with versions up to then. But I'm using it again because it seems a little less irritating than that Open Office change, which I can't find any way to fix in the menus. I suspect in that case Microsoft deliberately crippled it to force users to fork out for MS Office.
So perhaps this change will tip the balance for some users who want a new search engine. Perhaps a spy for Baidu was behind the change, or someone who's "family back home" has been influenced by Baidu.
