Allow me to get this straight... you would like to see a complete analysis of everything that's missing between the current state of GNUstep and 10.6? I can produce that, no problem but it is very boring and not worthy of either my blog or a kickstarter campaign.
No, it certainly wouldn't be worth posting in either place, but a link would be cool, even if it was to a mailing list archive where it was previously placed.
He certainly doesn't quantify this on either his blog, nor on the kickstarter campaign though.
