Am I missing something, or have the social buttons under the vote counter disappeared (network-wide)?
I must say, I know that a lot of folks (especially on SO) found the visual noise obnoxious, but I used them with some regularity.
Previously:
They were removed last week. They apparently saw "abysmal" usage rates and Kevin Montrose had been itching to remove them. I specifically mentioned that sites like UX likely use the sharing buttons a lot more than Stack Overflow (I was afraid SO likely heavily biases their opinion on the matter) but he said their usage was mostly the same across the network, and that while UX had more sharing than most it wasn't enough to keep the buttons around.
Remember you can share any post (question or answer) with the aptly titled link
link at the bottom of the post:
Note links shared from that URL count toward the Announcer/ect badge.
I've suggested the buttons be moved into the link
link under each post on Meta Stack Overflow.
Now this is offically implemented: Add social media sharing icons to the “link” popup.
Click the Share link below and post to share it; question or answer!
There's now a userscript to impliment my suggestion: Add Share buttons to the “link” box. Chrome/Firefox users can put this to use until SE changes something with sharing (if they do).
