In my case, two of the offers were from my network/friends. One was as the only developer for an exciting pre-incubator startup (I would still have been taking a decent salary), and another was for a company who gave me a decent offer and the head of engineering reached out to me personally whilst I was deliberating to offer some very kind words. The end result was that in all 4 cases I ended up caring about the people i'd be disappointing if I turned down the offer. So you're right that maybe the mass approach is better for avoiding this feeling, although it's hard to imagine taking it unless I was already out of work and could invest the time in such a high number of potential interviews.
