I love Vimeo. Great videos are on it, the design of the website is great, the embeddable player is great. Youtube looks like crap when compared to Vimeo, and that’s a given. If you have an iPad though, you may have noticed that Vimeo videos don’t play inline as Youtube videos do. I’m telling you, this was driving me crazy.
Fortunately, someone has come up with a temporary solution to make sure that Vimeo videos play inline before the official HTML5 embed comes out. You should go thank Squaregirl over here. I suggest you to bookmark it.
