If there is one thing I've learned about creating a marketing website with Kontagent is that... well, I shouldn't have bothered.
Not that we shouldn't be revamping our site, because the old one sucks and the new one is MUCH better (but far from perfect), its just that it has been an insane drain of our resources and time.
Made me realize why we decided to build Facebook Analytics and not Facebook Apps in the first place.
The lesson I learned (re-learned really) is that you should really pay attention to your team's DNA.
Do what you're great at, in our case building great Social Analytics for Facebook (and soon, MySpace and OpenSocial), and basically large systems (I work with a group of super-hard core Engineers), and outsource the rest.
The time we spent using our own resources to flesh out this website from conception to design to execution and revision, we could have probably saved thousands of dollars even by going with great local web design firm (or better yet, tap into any number of great international independent designers/firms that are cropping up everywhere from Russia to Brazil).
If you're a startup, there's a ton of great "virtual"/crowdsourced design and assistance services avaiable all over the web. You'd be foolish not to consider them... I'll follow up with another post that lists some of my favs.
