What's the Publish/Discuss/Translate/etc blocks for? They look like navigation but don't seem to go anywhere or correspond to anything.
They attempt to summarize the best features that MediaWiki can offer. Indeed, there are no detailed product descriptions to link to, but this is because we don't have them. I would say this is better than nothing. Currently you either know what MediaWiki plus selected extensions can offer, or you guess it by becoming a Wikipedia power user, or you need to connect many pages in mediawiki.org.
When i read that page it makes it seem like these features are available out of the box, which is kind of misleading. In particular claiming we have wysiwyg editing without mentioning visual editor is extremely difficult to install doesnt seem like a good idea.
Personally i thought the translate box meant that the mediawiki interface is translated into many languages (something we can certainly brag about).
Overall i like the idea of the redesign that you have in the uploaded file.
Bugzilla should have a prominent link. Sysadmins and other users who found bugs are not necessarily looking to 'get involved'. They found bugs and want to report them or find fixes. They're looking for a bug thing. Where is that?
+1 bugzilla is very important for downstream users who have bugs.
"Support" links to https://www.mediawiki.org/wiki/Project:Support_desk , which is where many MediaWiki sysadmins go when they have/find problems. Bugzilla is not visibly featured there, and it probably should be.
Getting support is different from filing bugs.
