Dilemma:

Twitter your thoughts and have trouble recording them for later reference. Twitter + custom search don’t play along.
Blog your thoughts and having to think of “I can’t have a posting that’s only 100chars long”.

Topic: the metaweblog API is more powerful that the API provided by Wordpress.
One of my customers asked me to create a function that would create a Wordpress blogpost whenever one of their PR-people finishes a customer-visit (funny enough, these visits are recorded in a shared Google calendar that’s updated via another webapp, web2.0 in action). After fiddling around with the wp-native API I found that the metaweblog is much easier. I still need to return to the Wordpress API for creating new categories but this only happens once every few months. Wordpress rulz!
