I installed phpGiggle today. Works like a charm :-). I only have one problem: I have to edit the phpgiggle.words.txt file every time I want to add something.
Wouldn't it be possible to add more functionality to phpGiggle? A small example:
In my blogpost I type this:
text bla bla bla [google:'wordpress'] and [wikipedia:'wordpres'] bla. Have you read [amazon:'The Green Mile']?
The [google:'text to search on google'] would be converted to the google search link. Same with the wikipedia and the amazon link. This way, you don't have to edit the phpgiggle.words.txt file constantly and you can easily create links to search engines, bookstores, etc.
Maybe this already exists (as another hack), but I didn't found it. I think Movable Type has this functionality with MT-Textile.
