I noticed that in narrower browser windows on the main wiki-page, some of the text (in the top box) is pushed below the splash-screen image.
Which is OK I'd say. Keep in mind that otherwise, if you are browsing with a mobile phone for example, you would need to have to scroll a lot to the right.
So yes, it doesn't look nice, but it doesn't hurt and is useful for mobiles. Actually, the splash screen should resize... ;-)
