On of the things that bugs me is the share buttons (facebook/twitter/g+) and they way they display after the page has loaded
It's not so bad when the share buttons are below everything else (since they can't be seen), but that isn't the optimal position for sharing. When the share sidebar buttons are above everything else, the sidebar moves up and down as the buttons are loaded
Almost always, they make the page / sidebar look like it's moving as the buttons display
It feels like the page is jolting as the user observers it (which isn't that nice)
If these buttons were wrapped within fixed hight/width divs, there would be no movement
On loading the page, the page would display as it should look, the side bar would be set out as it will be finally set out... the share buttons may not be visible at first but will load into the fixed hight/width divs as they are pulled out from facebook/twitter
This can probably be achived with something as simple as the css:
.shareControl{
min-height: 25px;
min-width: 100px;
}
