I like the marketing target, because it’s a nice summary. Useful for other types of readers. Also advertises hidden services.
The other changes… I don’t really mind. If no one else has a different opinion, feel free to make these changes.
I am thinking if it would make sense to design a totally new main page for a while now anyway. Takes 6 or 7 seconds to load over clearnet. Too much. Perhaps renaming https://www.whonix.org/wiki/Main_Page to https://www.whonix.org/wiki/About and doing something unknown with https://www.whonix.org/wiki/About.
I plan to talk to fortasse (whonix.org webmaster) about using varnish (http://en.wikipedia.org/wiki/Varnish_(software)). Maybe that would speed up things.
What perhaps would also help a lot would be using modern asynchronous / lazy page loading web technologies. Not sure if mediawiki is capable of this (without anyone patching it or its skin). Or perhaps there are other ways. Such as the approach by modpagespeed seems interesting. However, designing a professional high speed web site seems quite time consuming / skill demanding.
Varnish or not, page load speed or not, perhaps Main_Page is currently too heavy anyhow. Maybe too much content. Maybe too many screenshots.
