I don't know, I come back from trips after posting photos and videos of what I have seen and always get quite a few people saying how they love seeing all of the photos of my travels because they will likely never get to go to these places.

I've found over the years that a lot of people live vicariously through the photos I take, at first It made me sad because they should be out there living life and experiencing things first hand but now I have realized not everyone can for one reason or another so I keep posting, for me it isn't showing off or that I have an expectation that people will see and "like" a photo...it's really for those who enjoy seeing it and also as a memory bank for me...I have a terrible memory so I take a lot of photos of what I experience and can experience it all again when I see the photo in the future
