Interesting that they don't credit a couple of guys on the code they have used... Bad play do you think by the whitehouse?
I bet the plug-in authors are really proud that their code is on whitehouse.gov.
Update: Ah, saw the part you were talking about. I thought you meant the plug-ins in general. Nevermind :).
(Honestly curious...)
And no, I wouldn't mind if that happened to me. I'd be glad someone else found my code useful.
I'd prefer credit where credit is due - especially at such a high profile site.
Usually as a developer, its a common courtesy to credit any piece of code that you re-use that someone else wrote within your code. It is also usually required by the GPL or whatever other license the code/plugin is distributed under.
I couldn't give 2 tickles who coded the actual site, and not asking for a credit on the site UI. I do care about external people getting their credit though within the code, as that is only fair.
