Google seems to be bucket testing a feature that allows users to specify how detailed the summary blurbs in their search results will be. In an ongoing discussion here, one user comments that the three available options are Small (which omits a summary entirely), Medium (the current default length), and Long (which is around four times longer than normal). The changes affect more than just aesthetics - the Long setting apparently consists of both the standard meta summary as well as text pulled from the page itself, which could help users weed out sites with nice descriptions but little actual content.
