Yesterday, Adam Curry, the host of the DailySourceCode (Delta-sierra-charlie) hosted his 200th show using podcasting! Great stuff. It seems distributing digital content (in this case audio, expect video soon ;), is becoming easier by the day, and that users are growing exponentially.
A startup company called Odeo is still in beta (anyone have an account for me?) and is trying to expand this business. I found interesting this link to one of the founders' blog, explaining how the idea originated with him. Good entrepreneurial case study.
Check the startup's development on their corporate blog. And beta users are posting screenshots all over Flickr.
PS: these guys are also on Fortune magazine's list of the top 25 breakout companies in 2005.
