Maybe once a week somebody could compile the most interesting announcements into a single front page post? JayIsGames does a link dump once a week that works the same way. The effort would be relatively minimal, and you could further reduce the effort by encouraging announcements to fit some requested format in hopes they'll get in the front page summary.
let's be realistic here, that's not gonna happen. it's taken rinkuhero like 3 months (and counting) to post the results of the top games poll he held, and that's just a list w/ some links / youtube videos. most of the posts now are one youtube video and half a paragraph. anything more than that isn't happening, and even if it does happen, it will probably die in a week or two. i think journos already trawl the announcements forum, it's already a relatively easy place to get news from.
