Got that off my chest, moving on:
The video and landing page are very attractive. The video is solid but too long. While watching it, I kept mentally inserting edit markers. You can get this down to 30 seconds and it will be crisper and more to the point. When the bulk of a video is audio (you're basically just overlaying some audio on top of AE or Motion, and it looks great, but this isn't a complex story), make sure you're being as concise as you can be. If I were you, I'd edit the audio track first, cut some pauses and redundant phrasing, get it to 30 seconds, then match the animation accordingly. The end result will likely be way more successful and impressive. Brevity is bliss.
Other thoughts:
* You need examples of other sites, of the site builder tool (and of the data entry form) and of the backend.
* You are going up against Squarespace, Wix, Weebly, Yola and others. Wix, Weebly and Yola also have "free" options. I'm not advocating that you take that approach (on the contrary, I think when you do that it is often a deterrent to viable, paying customers because your main appeal is to the bottom of the barrel), but you need to be able to answer the question, "why not X." This is a saturated market, you need to be able to explain why your solution is better/easier/more-secure/whatever
* I want to know more about the company. I know this is just a Show HN, but before I would plunk down a credit card, I want some sort of idea (even if it is bullshit) of the people behind the site. As someone mentioned upthread, lay people fear losing their stuff if a host goes kaput.
Speaking of which, what is your data portability process?
- Good early launch page. Solid design. Now make sure you can actually answer real questions about your product!
