The best way is for SN to grow as community interests naturally broaden. Seems like it's just hitting its stride with its niche. I mean, I watched for a while before I started to see the point. So let more subs come perhaps through some sort of nomination/voting scheme.

Free software means you can do anything but it's an odd combo to have the drive to create a brand new forum based on SN software but not to want to talk about sats and end up competing poorly.
