On April 3, Apple released the newest member of its uber-popular family into the world, and technophiles were so jazzed that they snapped up over 600,000 iPads in five short days. But Apple-hungry consumers weren’t the only ones who were excited about the iPad—most* of the web’s biggest social players were pretty darned enthused as well, and they weren’t afraid to show it:

Google: To take full advantage of the large iPad screen, Google reformatted Gmail. The two-column display is basically an enhanced version of the single column Gmail for Mobile app that was created for the iPhone and Android. (Some Gmail users even argue that Gmail for the iPad is an enhanced version of traditional Gmail and are going to great lengths to make it their desktop default.)
Flickr: The photo and video sharing site gleefully announced on its blog that it would be making its videos iPad-compatible by introducing HTML5 playback. (Until very recently, nearly all websites embedded videos using Flash, but since the iPad doesn’t support Flash, sites are switching their vids over to HTML5 to keep up.)  
WordPress: WordPress also trumpeted its foray into iPad territory on its blog (a move that was actually quite apropos and vaguely existential). The blogging website has released a new version of its iPhone app that’s compatible with the iPad and comes equipped with all sorts of fun features like the ability to geotag blog updates.
YouTube: I found nary a peep about the iPad on the YouTube blog, but Apple was very vocal on the video giant’s behalf. The iPad comes with a built-in YouTube app, which, like big brother Gmail, is formatted to suit the iPad screen.
Facebook: Facebook has been making apps for Apple products since the beginning of time, so everyone was waiting to see what it had in store for the iPad. As it turns out, what it had in store was nothing. More accurately, a Facebook app was in the works for the iPad, but its life was cut short when its programmer took issue with the App Store screening process and quit the project. Some Tom, Dick, or Steve did create a Facebook app called Facebook Ultimate, but it developed a horrible reputation among iPad users (and infringed on the Facebook copyright to boot) and Apple has since removed it from the App Store. There is a bit of hope for the disgruntled Facebook user, and it comes in the form of http://touch.facebook.com/, which is a stripped down version of regular old Facebook that fits better on the iPad screen.
    
*Twitter is conspicuously absent from this list, and with good reason—the micro-blogging phenom didn’t go to any lengths to adapt itself to the iPad. Happily for tweet-o-holics, however, the App Store has been flooded with third-party Twitter apps (the ones from TweetDeck and Twitterific are said to be particularly excellent) that pick up the slack. 

If you’re one of the lucky few techies who’s already gotten his hands on an iPad, go ahead and tweet, blog, email, or update your Facebook status about how you’re tweeting, blogging, emailing, or updating your Facebook status with your all-powerful fingertips. Those of us old-fashioned mice-and-keyboard folks will be mighty jealous indeed.
