"Solid technical background and development experience with JavaScript, along with experience with UI AJAX frameworks such as jQuery, YUI, and scriptaculous and server frameworks such as Ruby on Rails and PHP;" Interesting. I understand needing to have a web dev background, but RoR and PHP without mentioning anything else seems to mean that they aren't targeting this evangelist at enterprise business using Java OR .Net? Or do they think this person would be prototyping and those were the fastest/best two to web dev with? They say "such as", but I don't think they just picked those two at random.
