Here's a real world example of someone making the switch from Ruby on Rails to CakePHP. 

"CakePHP is a web application framework, written in PHP (as all decent web tools are), and is in many ways very similar to Ruby on Rails.

Except it’s lighter (less cluttered), better supported (documentation, examples, etc), and deployment basically involves uploading 2MB of PHP files into a subfolder on your website (considerably easier than getting a Rails APP to run)."

The more I use Skype on my iPhone the better both of them are.  This is one of those cases where the sum is better than the parts.  Here's a grest example: Yesterday I was at the banquet for my kids' ski at the Dartmouth Skiway in Lyme, NH.  This is rural New Hampshire with cell service at the top of the mountain only but there's great wi-fi in the lodge.  My phone rigns and it's a Skype call from my oldest daughter visiting family in New Zealand. 

Here's a great example of how Barrie North from Compass Desings / Simpweb is using Twitter as an effective marketing tool.  He's running "The great #joomla tweet-a-way". It's taken Barrie a couple of months on Twitter to get there.  What might look like a quick and easy web marketing trick is actually awell crafted strategy that leverages Barries reach as a blogger.

Skype on the iPhone is cool.  No calls over the AT&T network but you can chat and do just about eveyrhing else without a problem.  Now Apple needs to put the camera on the front so we can make video calls too!  Loving the iPhone a little more everyday.  Barrie's wife calls it a "Devil's Box" ... she's just jealous.
