Considered it several times, yes, but wasn't sure where it'd go. I suck at building follower bases and I'm an old-fashioned boy anyway ;), so I have some bad memories about unlimited reposts and stuff.

Bingo! The best way to build out the network and really help people grow is to engage the network and get people interested.
Engagement is the #1 way to build out your social media network. I would know, I've done it more than a few times...
Sadly I'm constantly suffering from not being able to contribute to engagement on my behalf.
Resteems and comments of support are a good start...
