Edit 2 of today: Added a few clarifications I was asked for. ^^
Caved in, trying Instagram now.
And it's currently driving me insane by rotating the images in a way I did not take them. I don't even know why. I will figure it out eventually... And I will mostly use this account for work in progress photos (...because I don't know how to upload anything else yet d: ).
Looks better than FB too.
Good portfolio page, easy enough to use and looks nice. Though like most portfolio pages, the interaction is on a minimum and most of the time non-existing. If you want to go pro, this is a must-have in my eyes, mostly because possible future clients can find you easily. And they get a first look at your work too.
Not for daily uploads, just put your best stuff here.
