I have focused on primarily getting my IH community interested as well as sending out cold twitter messages.
Whoever follows me I would send an invite via Twitter or email. This has proved to be a great way to get the traction started. I do now have to get more "marketing" individuals over there as the conversations are getting deeper. Get manual!
will be an email campaign to my marketing network form LinkedIn.
build the PigeonHack concept. Community + Tools.
