I do. But I run a small development shop where besides engineering I have to wear a business development hat a lot. I've made some long lasting professional relationships with partners met via linkedin groups and I've been able to get at little bit of insight into people I'm going to be meeting with who I frequently don't know. I think its got more value for people in sales or business development then day to day engineers. But YMMV
