Given that a large number of people reported them as UFOs, it seems likely that they're fairly visible.

Personally, I'd find this a nuisance, not a source of excitement. I find it unfortunate that, when trying to enjoy nature, we are so completely unable to escape evidence of human habitation and technology.

They were much brighter and closer together right after deployment than in operation. Already, they've spread out and are now aligned in operational configuration so they're far less noticeable than at first. On par with typical satellites. I spotted them night before last, and it was difficult to see them.

As far as being able to detect evidence of human habitation and technology, that has been the case since the beginning of the Space Age. Choosing to find it a nuisance is, of course, a personal choice, not really something anyone can argue with you about.
