Sign up and connect your Facebook and Twitter accounts with Pinterest. This way you can instantly follow your friends on those sites. Hopefully they will also follow you as soon as they realize your presence on Pinterest. This means more people will see your pins and start repinning them thus allowing your pins to reach their followers who can then refer back to you as the original pinner and start following you if they like your stuff.
Make sure you don't just pin your Hubs but other stuff too otherwise you will look like a spammer. Also, look up WryLilt on HubPages and see her two Hubs about Pinterest, especially the one on MFP images.
