I use it in the same Rolodex fashion. I feel it also adds weight to a resume. If someone can find connections of actual people at other companies that I used to work with, it validates my resume, at least at a high-level. I've received countless job opportunities through LinkedIn. My current position, I reached out to a former colleague to join that company via LinkedIn. It worked well.
