on my website http://www.dancarrphotography.com/blog you can see that the YouTube button doesn't work, at least in Firefox 27.0.1 and Chrome where I have tried it.
It successfully brings in the follower count from YouTube, but the button doesn't actually link to my YouTube page.
Also the Twitter button isn't showing my follower count.
While I'm here though I'd also like to congratulate you on a great plugin. I absolutely LOVE the idea and the design. If I could get these two little bugs fixed it would be amazing.
