Is there a "best size for here" recommendation.
It's funny how all over the map it is. With social I'm finding different platforms encourage different sizes. On Ello it's common to see stuff 1400 pixels wide and larger. I'm now going with the flow there and doing 1400 wide for a landscape mode and 1000-1100 for portrait mode. On other platforms I see it's not as generous. Lovely to see stuff nice and big if you're on a large screen device and have decent broadband. On the other hand, I often think of a pro photographer friend who's all but given up posting anything on the net for fear of piracy. And when he does post, it's no bigger than 800 pixels wide - often smaller than that. When he gets into that mindset of "I'm not going to put anything on the furshlugginer net" I have to wonder what the point is. Folks like him are so talented, they deserve a wider audience. Yet there's this whole other newer mindset which sees all data as being fair game - slice and dice other people's work as you will and make it your own. There's no stealing, only repurposing. I have mixed feelings about all these different points of view and see no clear way to resolve all their differences. I hang out a lot at Urban Toronto. They've recently changed their platform software and have been encouraging people to use their file uploader. They then resize those images to fit their standards template. Me, I still like the control of using my own hosting sites. Most of the places I frequent are image-heavy anyway so I've given up worrying about people on limited cell plans or, heaven forbid, dialup. Generally I try to make stuff fit whatever the prevailing norm is on a given site. Occasionally I slip up. Too, it's a pain to save to different sizes if you're cross-posting images to two or three different sites.
