1.) The larger frame around the text is going to make any long story on the front page, or a long post on a thread, take much more vertical space and will be harder to follow and read.
2.) "On the Boards" (frontpage) is a smaller text size, might be troublesome for some.
3.) As an office worker, the old format of the site (non-flashy) was conducive to sneaking reads while at work. With the old format, if I scrolled past the header with the logo - the website could be mistaken for any number of random sites that would be acceptable to read at work. Now, however, with the massive purple frame and the ads at the top, I will likely not be able to do much reading during work. Clearly this is personal preference and problem I need to resolve on my own, but the old format of the site made my day much better.
4.) The pages including Puma ads never completely load. There is the constant "revolving circle" at the top of the website insdicating that the site has not loaded. As far as computer performance, or actual meaning, this revolving circle doesn't have any relevance for me but it is annoying.
5.) The ads are effective. I like Usain Bolt and I like Puma's spikes and their apparrel. My first reaction was: I have to get some more Puma gear. However my secondary reaction, similar to at least one other previous poster, was: I will never buy Puma gear again unless they can make this transition a little less dramatic.
6.) Please do not change the logo.
