I have no objection to the current wiki being the front page, but there were howls of dissension when it was suggested before I thought, over the fact that it was too unclear and unfriendly.
I don't think that discussion was particularly related to whether the wiki reached the front page - just a general feeling from everyone that it needs a new theme.
Like most, I agree that the theme needs freshening but the current one is usable and my feeling is it's better to have an accurate but slightly busy front page rather than a now-dated page which makes it somewhat harder to reach the latest content.
Or do I remember it wrong and that's what we've been waiting for?!
I'm more than happy to stand corrected - the beer over the years has not been kind to my memory ... ;)
