Loyal Cleantech Investing readers -- We'd like to invite you to participate in a very brief year-end survey, to share your thoughts on 2007 and predictions for 2008.  This is your opportunity to share your opinions on the market with your peers and colleagues in the industry. Please click here to take the Zoomerang survey.  It being a busy time of year, we've kept it very short, it should only take you 5-10 minutes.  The deadline is a week from now:  Friday, December 28. To add to your motivation to participate, GreenTech Media has kindly offered up a few GTM USB memory sticks -- perfect for sharing your business plan or marketing materials at your next cleantech networking event.  Also, demand response/ demand control system developer Powerit Solutions (an @Ventures portfolio company) is also offering up a few coffee mugs to participants as well!  A few lucky, lucky winners will be randomly selected from the respondents, so make sure to include your email address (spam-free, I promise) at the end of the survey, so I can get in touch with you if you win one of these highly coveted prizes. So take the survey today!  The results should be pretty interesting, stay tuned...
