I take photos. And I do publish shots to the flickr.com. Yes, flickr, not instargram. I also installed flicrk app to my phone.
The funny thing is: organize albums, share photos to groups, see comments and recent activities is much simpler and faster in android app than in website.
This is really unusual.
PS: upload photos is still works better in web; probably because I usually process my photos on laptop, probably web interface is really better for this.
