Username/Avatar and Share indicators on bottom of posts
Often I see something I like but I didn't notice initially who posted it, so I have to scroll up to check the username/avatar and to see if it was a direct post or a share. I think having that information on a small column at the bottom (as well as the original information at the top) would be nice, would avoid that checking of information. This is true especially on long posts. But it's not really a problem, just something that might help me with my diaspora using habits.
This is probably better resolved by visually unlinking the author information from the contents, and make them position: sticky when scrolling, so this information stays visible when scrolling. However, that's quite an UI refactor. :)
Maybe just making the avatar sticky could be enough, it can always be hovered to check username.
On the mobile version, there is first the image posted, then the author info, then the text content, and then the interaction panel. On facebook, the author is always before the content. This is something we will look at when doing https://github.com/diaspora/diaspora/issues/7995 I think.
