It's a little of that, and almost my particular job skills are still in demand right now. Just putting "looking for work" on my LinkedIn profile got the contacts flowing.

BTW, I did not, never, not once, apply to any jobs listed through LinkedIn this time around. I did that before and it was utterly demoralizing. Their ads were like "subscribe to LinkedIn Ultra and move to the top of the list of 9,000 people applying for this role!" I've never gotten a single hit from applying for a tech job through LinkedIn. I don't think that's actually a thing.
