Forum postings on front page of ardour.org
I think a great idea would be if the latest postings(maybe 10 or so) from the "Ideas for Ardour" and "Made with Ardour" sections were posted on the front page.
I think the the left sidebar would be a good candidate since it's very empty and needs some loving... :-)
This would give people an immediate idea on the active development of Ardour and maybe they'll be more encouraged to dig in(and maybe even contribute).
In general, I think that new visitors to many webpages rarely look at all the sections of a website inside-and-out. In many cases, they don't even get past the front page.
