One of the blogs I find of great informational value is The Internet Stock Blog ("news and analysis of Internet stocks, no buy or sell recommendations," it says in its masthead).
Recently, the blog started including a most useful new service - full transcripts of some of the most popular companies' earnings conference calls.
What's especially useful is that all these transcripts are in one place, they're free and you don't need to register anywhere.
One interesting one - the Q&A from eBay's Q3 2005 earnings conference call. Useful to read, especially the Q&A re Skype which you can keep in your mind when you read this story in eWeek headlined eBay CEO: Voice Phone Calls to Be Free Within Years.
