I am technical and articulate and have been slowly sifting through source code to understand things better, BUT I don't feel like I could field questions from cryptographers or software engineers without imploding.  I can talk about Nxt, and some of the challenges it faces, but the CfB-BCNext filter is a little too opaque to be useful for understanding the deep fundamentals (after only two months of this stuff, the exhaustion is overwhelming: "the source code is the whitepaper!", "community must decide", "Enigma!", "Tease!", "u are incorrect check thread for answers plz", "wait for third part of plan", "many riddles in the source if you look", etc.)

I'd say some nice things about Nxt, and then one guy would raise his hand and ask "can you explain the rationale behind basing a cryptocurrency on a mix of Curve25519, EC-KCDSA, and SHA-256 when no papers exist that assess the semantic security of that particular Diffie-Hellman key exchange algorithm, and it is has only traditionally been favoured for its calculation speeds?", and I would suddenly smell toast and collapse into an apoplectic heap, muttering "just ask Beyonce it all comes from Beyonce" and weeping.  THEN watch the price.

It's a real Catch-22.  Getting a chance to take part in a panel that would be included in the (always awesome and SO VALUABLE) Let's Talk Bitcoin podcast is *exquisite*, but the person to talk about the advent and future of metacoins is currently living in Belarus and busy until April.

MY VOTE would be for someone like wesley, ferment, opticalcarrier, rickyjames or ricot.
