There's just more demand for that sort of thing than supply, so I don't know why they would be looking on Linkedin for it. 

you can network with wholesalers.You can purchase lists and compile lists from city and county for 60-90-120 days late on mortgage, pre-foreclosure, delinquent taxes, water cutoff, code violation, probate, divorce, high equity, etc. and mail or cold call.Other methods are driving for dollars, door knocking, wholesalers, craigslist, Realtors, FSBO sites, expired listings, foreclosure sites, put out bandit signs, billboards, newspapers, other offline publications.You can use pay per click/adwords, facebook, Linkedin, Youtube, and other forms of online and social media marketing.

Lets connect here and linkedin.

(do the same with Facebook, Linkedin, etc) Its an easy way to find buyers in any market!

Online with Craigslist, Postlets, Facebook, Twitter, LinkedIn, all that jazz.

I've been playing with Google Plus + for about a week now, and I have to say that in my opinion, it takes the best of Twitter, Facebook, and LinkedIn, and brings it together in one well-thought out, brilliantly executed general social network.

The LinkedIn groups are kind of the same way...not really sure how to correct for it.

Plus those threads that are linked in that post now get brought back to life every now and then with a comment or question - and that is also a good thing IMO, because it places new discussion on the tails of the prior discussions and builds upon that or clarifies that discussion.There's nothing to stop anybody from doing something similar.

I would say you have more in common with LinkedIn than Zillow but I could be wrong.

You could also list your group on Yahoo and LinkedIn.
