OH MY GOSH!!! That is EXACTLY why I came to the Site & Customer Service category just now! On my laptop last night, I thought something was wrong with my touch pad. On my phone, I thought it was a slow connection. But, now on my desktop, it's not working either. It takes FOREVER to register that I've clicked on it, and by the time it registers, I've clicked again and the Like goes away.

I use the like for things I like, things that are funny, things that are helpful, to let people know they are not speaking into a void, and to show a quick thanks for responding to me. So, I use it a lot and all that to say, YES, the like button is sticking/delayed/whatever and I'm so glad it's not my imagination!
