Twitter is a free social networking and micro-blogging service that enables its users to send and read messages known as tweets. Tweets are text-based posts of up to 140 characters displayed on our Twitter profile page, helmetsdotcom, and delivered to our subscribers who are known as followers.  Users can send and receive tweets via the Twitter website, Short Message Service (SMS) or external applications. While the service itself costs nothing to use, accessing it through SMS (or your cell phone) may incur phone service provider fees (check with your carrier).  Simply click on the link above to see our recent tweets.
