There's an office building right next to LSVP's offices, and they have an entire suite there that the teams use. It's actually a great space, although when we were there the AC was off during nights/weekends.
John is honestly a great guy and we had an excellent experience with the program. I'd highly recommend Lightspeed for anyone looking for an alternative to the summer incubator route (though it's important to be aware that, as John states in the blog post, it's NOT an incubator.)
I'd have to heartily agree with this sentiment. While oftentimes I think we do see engineers get marginalized in favor of "business" employees or designers to disastrous effect, it's important to recognize the importance of UI/UX, especially on consumer-facing products. While Apple and its extreme focus on UX is the most prominent example, many web startups have seen success due to a combination of good marketing and design (Tumblr, Facebook (vs. Myspace), Instagram, and Flipboard come immediately to mind).
