I feel that SpawnCast is a podcast that does a lot of things right, but something's could be changed/improved.
First, I like their choice of topics that they talk about. They stay on topic and talk about it extensively, giving valid points and opinions. I have also enjoyed everyone that has been on it thus far (e.g. RGT and Evan); all bringing something new to the table.
However, although I like the amount of detail in each conversation, I would prefer if the podcast was closer to an hour long, rather that 2, and if I'm really being picky the audio quality could be a bit better (but this may be just me).
