Cool music. Quite enjoyable production. This could be good.
I really like the smooth low volume background music while you talk. It gives a pulse and a beat to the podcast.
Make a list of the topics you're going to cover. Announce the list of topics at the start of the podcast.
You announce each topic as you're about to start it. This is good. Keep it up, stick to it like glue.
Next up: "Open Transactions." -> "Allright that was open transactions."
Next up: "Gavin Andresen has a proposal for credits for testing changes to the Bitcoin Client."
Next up: "The London Bitcoin Conference."
Neat, but make this list known at the very start of the episode, preferably before the first musical segment to catch the listeners attention.
Would be good if you announce the name of the artist and the song you're about to play in advance, like, you know, on radio.
Clear your voice in advance, drink a hot cup of tea and warm up your vocal cords, try to avoid coughing in the mic several times every minute.
(When you need to cough, mute the mic, cough, unmute. Live radio always has a cough button. For good reason.)
You have a really nice smooth voice, but you could be more focused and "less laid back".
Make an effort to sound like what you are saying is important, and it will sound like it is.
Project your voice, think of a radio host, try to speak more like a radio host,
do a quick dry run, warm up mentally. Get in the zone before you go live.
Keep a fixed distance to the mic, lean more towards the mic perhaps.
Perhaps record each session in several segments, if this doesn't mess with the music.
You could cut and paste the segments together, add music in post production.
This way you can do a retake if you stumble or mumble or stop.
--> Less... like... uhms, and uhhhs... and uhh.... small pauses.
Finally, do a recap / outtro / see you next time at the end.
That was pretty much everything, and this is quickly starting to sound too much like actual work so I'll be sure to stop here.
Really promising start. I'm looking forward to the next episode! Yay! Go you!
