[Martin, if I misrepresent your views below then I apologise in advance.]
Thanks for the feedback so far everyone. We're looking forward to reading more. I'll start to answer some of the issues with some general comments.
General: First off I must say that any praise for the site should predominately go to Martin. He's done the vast majority of the work and I've just been around to - figuratively - make the tea.
Images: As Martin said, none of the images are set in stone. They can all be changed and we would hope that anyone who has a better version of anything that's there will suggest something specific or, even better, post a link to something that can be used instead.
Text: All of the text can be changed. What's there, as Martin said, is just so there is something to discuss. We decided to add something from the real world instead of just using lorem upsum or bullet-pointed question marks to get the ball rolling.
Design: The overall design is a bit like custard at the moment - not totally fluid but, at the same time, not quite set. (You could say it's a non-Newtonian website!) The eventual product will probably look much like it is now but most of the details can be - and probably will be - changed. So, whatever you don't like, speak up.
And now for the individual comments:

I think you're right that the link to the bug tracker could be put on the footer (and therefore on every page). It's important enough to be there. I think the "Get Involved" section might change into something like: Write some code; Change the interface; Get the message out; Report a bug. Or something like that. Something more "active".
The large image on the home page isn't unusual these days and most people will have seen something similar (
http://foundation.zurb.com/ ,
http://www.libreoffice.org/ , etc.). If the browser doesn't show scroll bars then that's probably an issue with the browser. Most people know that web pages can scroll and will try to do so. If someone doesn't have the technical know-how to use their browser then they're probably not going to be able to use Scribus.
I agree that the "standard headers" should be shorter. I don't know how easy/difficult that would be to achieve within the framework being used (that's Martin's area of expertise). I think about half to two-thirds the current height - probably more towards half - would be reasonable.
The current "standard header" images are just place-holders for something better. If you - or anyone else - can think of an image that says "features" or "download" (or any of the other things) better, especially if they are relevant to DTP, then please say so because it's difficult to think of something good (they're already at the second or third versions).

I agree that the sponsors should have more prominence on the home page. Some kind of carousel may be possible (again, that's Martin's area).
I also agree about the text on the home page image being wrong. But what's the Scribus tagline? Inkscape - as you say - has "Draw Freely", Blender has "Creative freedom starts here", GIMP, well GIMP doesn't seem to have one. So what can Scribus have? "Publish it now", "Get it published", "Layouts made easy", "Fast and Free Layouts", "Get laid for free"! (Obviously they're all terrible suggestions.) Maybe someone can come up with something good.
The "About Scribus" section is indeed too wordy - it was taken from the current Scribus web site - and should be re-written into something more "enthusiastic", "upbeat", and "active", and far less technical. Which direction do you think it should go in: What people can do with Scribus (which is then repeated later in this page); or: What Scribus can do (which is then repeated on the features page)? It's difficult to know what to put there. Maybe a mix. If anyone has some good text to use then please say so.
For Features, can you say what you would not put in there or would write differently? It's difficult to know how to respond if you don't give us any idea of what you think is wrong. I know you don't really want to get involved in anything to do with the web site so It's great that you've taken the time to comment but it would really help if you could give more than a vague hint. (You can send me suggestions in a private message if you don't want stuff to go public.)
For Learn, can you say what links you think should also be there? Or are they a secret? It's as if you said "I know how to put this fire out" and then ran off into the distance.

For News, yes, that's probably the most difficult page to get right. All of the other pages will be fairly static but both Martin and myself - if I've understood his feelings on the matter correctly - feel that this page should be kept "buzzing" with new information. What's been fixed? What are people working on? What's coming up? This page should show people that Scribus has an active community and is being updated regularly. They are more likely to give it a try if they know it hasn't just been left to rot (as so many other projects have been). This is something that Kunda was doing very well until not so long ago.
If this doesn't become "the" Scribus web site then there's no real point in it existing. There's no point in having two Scribus sites, that would just be confusing for everyone. "Hey, have you seen the news on the Scribus site?" "No, which one?" "The main one", "Which one's that?" As far as I'm concerned, either this becomes - or evolves into - the "real" Scribus site or it just goes into the trash. I have no problems with that either way. Martin has put a lot of work into this and I'm sure he would be disappointed if it wasn't used but I warned in my second post in this thread that it could all be for nothing in the end.

Thanks for commenting. If there is anything specific you think might need changing then don't hesitate to speak up. Even if it's something small. Sometimes it's the tiny details that make the difference.

I've added some issues to the GitHub project to keep track of what's been commented on so far.
