The academic job market can be unforgiving, and for those who also have industry leads/offers it can be helpful to know whether there may be future offers from academic institutions when deciding whether to commit elsewhere. Even without industry offers, it isn't like all academic job offers come in at the same time and you may be second pick at your preferred institution so it could take some time for a possible offer to come through. If you're still getting website hits from a place it's a fair bet you're still under consideration and you maybe don't want to commit elsewhere.

It's not really about an ego boost, and in any case, egos can take a pretty major bruising during the very anxious weeks.
