Aggrandize
1. To increase the scope of; extend.
2. To make greater in power, influence, stature, or reputation.
3. To make appear greater; exaggerate
Example:
Seriously, I think personal blogs are one of the most self-aggrandizing activities of our generation. More so than MySpace. With MySpace, you are at least not pretending that anyone cares about you beyond looking at that hot picture of you covered in nothing but whipped cream. With a personal blog, you are pretending that people care enough about you to read your random musings about a random selection of stuff that’s going on.
