SnipSnap Developing: Fresh Macros 
Most of the blogs - specially the widely adopted wordpress - are filled with macros that support nowadays common services, like del.icio.us, youtube, wikipedia, digg, etc.
I felt that snipsnap also deserved such macros, I felt that my blog deserved such macros. So I'm currently releasing two macros:
Youtube MacroThere's not much to say about the youtube macro, mostly it takes the ID of a youtube video and renderers the embedded object. To know how to get the ID let's examine an youtube URL. Here's how they look like:
http://www.youtube.com/watch?v=ID
So for example, if I wanted to show the Super Monk video - with the URL:
http://www.youtube.com/watch?v=_U4oO76ml28. I would type the following command:
{youtube:id=_U4oO76ml28}
Result:
TagometerExamples of tagometer can already be seen in the Domain Driven Design posts, such as
Software Developing: Domain Driven Design looking at Persistence.
There are also two ways of displaying tagometer, inline or block, that can be said to the macro via the parameter inline, which can be true or false (defaults to false).
So here is an example of tagometer:
{tagometer}
Result:
Any suggestions about these macros or new ideas for others are always welcomed.
