I hate to be "that guy", but what about turtle4's observation [1] of some TOS items? Seems like your post may be crossing some lines?

NO PRESS RELEASES. You may not issue any press release or make any public statement about the Marvel API (and related Content), Tools, the inclusion of any of the foregoing in any Apps (yours or others') or these API Terms of Use without Marvel's prior written approval.
I'm hoping you're just kidding. Would making a forum post really violate their TOS? I would consider this a "public statement," but I am not a lawyer.
I am surely biased, but it's a pretty fun way to rediscover comics you might have forgotten about.

UPDATE: The code that queries the API (while messy) is entirely written in client-side JQuery, so feel free to view the source.
