I saw reference in another article that the Toronto Star had recently removed registration from its website, the start of a new trend that is good news for readers and encourages bloggers to link to articles. I managed to hunt down this December 13, 2005 article: Toronto Star removes registration from thestar.com.
If you haven't looked at thestar.com lately, you should. They have added links to blogs by columnists, a "podcast" section where some of their writers post one-off audio segments, they have RSS feeds for various types of news including headlines, and you can also register for alerts (probably the same as the RSS feeds, for those not yet using them).
They've got the right idea. I wish the Globe and Mail and National Post would follow suit with making articles more accessible! I have long felt requiring registration has alienated readers and discouraged people from citing their publications.
