I think a wiki of useful software and communities would be great! On reddit, weekly threads were often designed to corral posts so that the subreddit wasn't flooded with similar topics. It seems like that's not a problem here, so weekly posts would have to be pretty open-ended to spur discussion. For example, this week there could be a Black Friday Hardware Deals Post or something (e.g. I hear those 18TB WD hard drives at Best Buy are decent starter NAS material). Next week, there could be a post about shucking the drives.
