What the other poster said, except that "suckiness" is clearly a noun, not an adjective. Like "kindness" or "carelessness".
The suckiness of the above poster's understanding of basic grammatical terms is quite apparent.
Stems from the word suck, or to suck. An adjactive meaning something is really crappy or sucky. Something that is completely featureless and super lame.
The suckiness of jBuilder is beyond compare.
