A Proposal I believe the main page of Wikipedia could be make a great deal bolder with a couple of small changes. The top boxes (In the News) and (Today's Featured Article} are not bold enough - the headings should be in BOLD and ALL-CAPS and the typeface should be at least 2 points larger, with the blue news headlines possibly flashing or just scrolling along the top of the page in the manner of a news ticker, also there should be a much larger image on the page, and the font is a bit square, should be replaced for something a bit more fun. I think this would get more people keen to view more parts of the site.
I have an idea. Currently the animated GIF is one of the most popular media formats on the Internet. I believe the front page would be more vibrant if an animated GIF of reasonable size (about 350-400px) was placed in a prominent position. These animations would illustrate some of the key topics of Wikipedia, and could possibly accompany the featured article. Also if music was mentioned on the Main Page it would be good if it could play that music when you view the main page. I can see some of your points about how the flashing and scrolling text may be a bit distracting but it would have the benefit of making the main page stand out and the content seem more enticing.
