information zombie

1. One who continually, mindlessly, and voraciously consumes information (usually in electronic forms such as podcasts, news and entertainment sites/feeds, blogs, etc.) without the intention or effect of learning, retaining, or integrating any of what is read or heard.

2. Someone who consumes information just for information's sake

NOTE: Analogous to a traditional zombies in that the abstract object of consumption (ideas) is generated by the activity of the traditional, physical object of zombie consumption (brains).
