since we're in different fields this might not be useful, but i always strive for the summary plus approach..not necessarily bringing up a *new* subject, but widening the scope so to speak.

in my diss, forexample, i examioned a text not quite within the scope of my field whose reception in particular exemplified and illuminated all the issues i had argued throughout. i this had a convenient way to bring them all in and show that the issues were larger than i had 'prioven'...not sure this makes *any* sense without specifics :-)

as a reader i like case studies/examples/personalization bioth in intro and conclusion and i think looking toward limits of your research/new venues that it has opened up it always neat.

good luck!!!!
