1 year, 2 months ago: I started a B2B group on LinkedIn last summer and it is hard to get going. It takes more time than I originally anticipated. I did some research and discovered there weren’t very many groups dedicated to helping companies from industrial sectors with Social Media endeavors. Yet, there were many of those companies who wanted to try and use Social more effectively.
I have been able to get over 80 people to join the group, but the hard part is to get interaction going. I try to post at least a couple of times a week and ask questions, but there are very few responses. I try and share thought-provoking articles relevant to using LinkedIn and Social in B2B.
I also participate in a number of other groups and have invited their members from time to time – very low key of course. I don’t want to appear to be “poaching”.
The group is called Social Media for Industrial Companies (I know, really clever huh? 
I would welcome any ideas and/or suggestions.
