JAMISON:  Are you guys going to do a doo-wop chorus? I feel like with you all sharing the same microphone, we need some sick vocal harmony.

MERRICK:  I wouldn’t mind starting a JS Jabber a cappella group.

JAMISON:  Hey everybody and welcome to JavaScript Jabber Episode 68. I am your guest host, Jamison Dance. Chuck is at LoneStar Ruby Conf this week. We have Merrick Christensen.

MERRICK:  What’s up?

JAMISON:  We have Joe Eames.

JOE:  Hey there.

JAMISON:  And we have an incredibly special guest, Aaron Frost.

AARON:  Hello.

MERRICK:  [Laughter] What?

JAMISON:  And he is not British.

AARON:  Coming from across the pond.

MERRICK:  Once you’re gone, I’m going to start using that as my greeting.

AARON:  Well, I wish my name was like that one guy, the Allonge, Reginald Braithwaite.


AARON:  Where it’s like your name’s in British.

JOE:  Yes. Your accent, no. Oh, I would have my name be Benedict Cumberbatch.

AARON:  That’s pretty British too, that name.

JOE:  That’s a very British name, yeah.

AARON:  Wellington something.


JAMISON:  Then you would be the archduke of JavaScript.

AARON:  Yeah.

JOE:  Oh, that would be an awesome title.

AARON:  That’d be great. It’s a good title.

MERRICK:  So Jamison, do you want to talk about why we have Aaron on the show?

JAMISON:  Yeah, I was going to ask him to introduce himself.

AARON:  Oh, great. I’m a web developer at an awesome company called Domo.

JOE:  But what’s your official title?

AARON:  Officially, I don’t know. What are you playing at?


AARON:  Maybe an open web strategist.

JOE:  There you go.

JAMISON:  Social media expert?

AARON:  I don’t know. But I work on our UI team and we’re getting ready to push out a really awesome release that everyone’s going to love. I’m also an author. I’ve published a short book with O’Reilly in May and working on another book.
