Hugh Hewitt is among the leading conservatives who are urging conservative or libertarian public officials and commentators to start using Twitter. The Top Conservatives on Twitter website offers a wealth of feeds to which one can subscribe. If you would like to subscribe to my feed, it's @davekopel. (Go to http://twitter.com/davekopel, and click "follow.") My twitterfeed copies the content from my RSS feed (http://www.davekopel.org/feed.xml), which supplies links to my latest articles; the twitterfeed also includes my random thoughts on various subjects. Some readers may be interested in the twitterfeed of my Independence Institute colleague Ben DeGrow (http://twitter.com/bendegrow), who writes on Colorado education issues.
