A short and sweet lesson here.
We mentioned above the importance of omnipresence across platforms, the repurposing of content, but here's a perspective on where to start:
To grow faster, focus on reaching critical mass on a single platform, then deploy your earned capital into a new investment.
Example:
Spend 6 months mastering one platform: Build an engaged audience that you can leverage into new platforms as you dial in your message.
Spend 6 months trying to grow on 4 platforms: Split your focus across 4 groups of people, asset production, and community management.
Who's going to be better off in 6 months time?
