When you were just about to do something in the internetz, but you suddenly can't can't because you have instantaneously forgotton what it was due to overstimulation, consider yourself netblitzed.
Can also be used in situations when your brain simply does not work properly for a while. Spelling errors abound. Log-ins fail. Entire email accounts are forgotten. For example, see paragraph 1, above.
Author of netblitzed intended for a straight definition, but somehow, errors/netspeak crept in. He/she had themselves, indeed, been netblitzed.
