I tihnk a lot of judgment is based on “selection bias”. As Avira is saying – A chusid travelling for a vacation and instagramming is not representative of the klal. And what Gadol sees as “changes” may simply be more mainstream community joining in.
Goldilocks, great tips. If you need to post, do it after you are home, not before you are travelling. Crooks are scanning for this info.
But maybe think what is important and post that – a kid with a sefer, someone helping a grandma cross the road ..
