Academic's request for Internet/politics poll participants

I've received a request from Barbara Kaye at the University of Tennessee - Knoxville for participants in an online survey of how the Internet affects political activities and views. Like any online survey, this one is by definition non-random. But I believe it is  legit, and is a continuation of surveys done after the past three presidential elections. Here is an abstract of a paper based on a previous survey.

She says she is "specifically looking for liberal/progressive respondents." If you're interested, the survey site is here. Survey is open until November 26.
