You should add to your marketing more info about how you are good in handling traffic and most importantly why. In a way that will make sense with both tech and non tech types. (Non tech has no idea what aws is or a cdn is for example). I've looked at your site a few times (even right now) and that isn't the thing that stuck in my mind from your marketing. The takeaway for me was "expert at WP" not necessarily "expert handling of traffic and here's why". I'm not saying it's not mentioned. I just think that point has to be driven home better.
We're (literally) working on a website refresh right now, which hits that and other points. Sample factoid: One of the customers was on 20/20 recently and sustained 2,500 requests per second for 15 minutes.
Boring technical details: Varnish caching, automatic load balancing, redundant servers (beefy physical hardware to avoid poor disk performance on virtualized systems), "Death to KeepAlive", etc.
I would add an additional bullet to the home page adapting a key statement from that page where they said "sit back and be happy you're not having to do all this yourself."

(Hey, why are we so fast, secure and scalable?)
Sit back and be happy that you're not having to do all this yourself
Thanks for the suggestions. We're still in the process of updating things, but we'll make "Compelling for non-technical users who just want things to not break, comprehensive for technical people who want to understand we're not snow-jobbing them." a priority.
