Very difficult to choose here, as I REMEMBER hearing Solver, Jon, Methos, Barry, Blake, & Elhoim. I voted for Jon for the info he provided, despite the horrific sound quality (due to tech difficulties, such as his computer fan). I listened to parts of that 2-3 times to try to glean stuff from it.
I listen partly for the informational aspect of the content. Therefore Solver (for his pre-3.13 unofficial patch), any Firaxian, & Blake .... BTW, is Bhruic going to be on in the near future (nudge, nudge)?
