Many of my real estate friends, mainly people I've met from Active Rain, have joined groups for their geographic communities and for real estate professionals. I've noted in this niche that face to face meetings between formerly online only friends is huge right now. Meetups and Tweetups and the sort are all important.
For me personally Facebook has three key priorities:
- To maintain an active presence for my three key social niches - real estate, politics, northwest indiana
- I let twitter posts roll into my status updates automatically - thus a lot of status changes to my profile every day - and these have tended to create some active debates in news-feeds amoung friends. Early on these debates were entirely political friends, but recently real estate and northwest Indiana friends have joined the debates too.
- Business Development - our consulting practice offers business development consulting to a couple small businesses. I use Facebook to professionally reach out to potential new businesses, I find linkedin still doesn't have the attention of professionals.
