I am not really into podcasting, most likely because my daily habits don't give me the physical time to listen to them - commuting is out of question as I live a 10 minute ride from work, and don't like to listen to anything when working out, I'd rather think. That is if we consider that podcasts are to be used for filling up the voids given by deadtimes while commuting, exercising, etc. Otherwise, they're either a gig you're passionate about, and that means you have the free time to dedicate, or you make money out of it, which is something that I still haven't figured out.
But this doesn't prevent me from watching closely the space, I even have an Odeo account, which seems quite an interesting service btw. Honestly, besides not being an enthusiast I guess that I am still not seeing the money into the space and podcasts don't really solve an immediate problem of mine, even though Nicole's were quite useful before Reboot the other month, for example.
Anyways, the related infrastructure seems to have picked up frenzy -- a quick example would be Stefan's: from a row of 8, 5 had iPods on his transatlantic airplane. Also, Fred, definitely an enthusiast of the technology, seems to make a good use of the podcasts. Besides the family shows he puts out every week, he started listening to entrepreneurs pitching him on various projects while he is biking. Which is neat.
Looking forward, after blogging as push to publish podcasts may be the *next thing*, as well as online video (webcasts are a different cup of tea), but I do have my doubts, I see it more as hype and wishful thinking. For the time being - and this is what makes the difference when making early bets, right?

For more on the importance of podcasting and what it all means... http://www.itconversations.com/shows/detail211.html PS: Podcasts _are_ fun.
Ah, I know IT Conversations and Doug Kaye's show, I've linked to their shows several times on this blog, just look into the archive, there are also plenty of posts about what they are, etc. Not the point, though. As for podcasts being fun -- see my above free time to dedicate point, obviously it's a matter of taste, I was rather talking about podcasts making use of a lucrative business model. It may be a nice to have, definitely not a must have.
