Wondering why there are so many places where to put ones' photos?

 

I have several accounts that allow me to put my photos in different places. What's the difference between flickr Simon Luisi and Instagram Simon Luisi?

  And most importantly, does the question matter and if so how so?

  I guess that just by preparing this post, I got some answer. It seems easier to download a picture once it is on flickr than it is on Instagram. Now, that's a big deal.
